In this video I test the Cobra F9 Speedback Driver with weights in, one weight out and then BOTH weights out to see what difference there is in performance!

Could you put the screws in without the weights? And see how that reads on totals
I have been changing the weights an shaft adjustments I have come up with 2 grams in the back 8 grams in the front shaft at std draw with a 45 gram regular shaft it works great
I'm guessing you can at least put the screws back into the holes.
I have 15g front and 5g back and 2.5g in middle of my 0811 x. PXG
you need to get your launch angle higher to get more distance , figured you would know that by now . 🙂
Im hitting same ball speeds with an epic flash and a mitsubshi stiff flex with same launch angle. But cant get past 260 meters with out absolutely going after it and even then suffering.
I can get my ball speed to 170 plus MPH and only just gett past.
Do you think its-
range balls?
Top tracer at the range?
Or not enough weight ?
hi michael, i have one of these drivers, i cant get on with it, i dont know where the ball is going! tried moving the weights & tried moving the loft both ways, cant understand why!!
Can you really count the shots hit with no weight? No criticising but they looked like very poor strikes compared to the others ? I would be interested to see the results from consistently hit shots. I say this because I have this driver and have taken all the weights out and I’ve been smashing it miles with great flight and distance. I’m not sure I go for all the tech the companies try to sell us. Most clubs can be hit well with the a proper strike put on them don’t you think. Hence why I made my first point about poor strike . What do you think please ? 👍🏻
Well your driver with all the weights removed doesn’t show us what we want. U struck it horribly. Would like to see what would happen with a good strike.
Excellent video. Thank you.
Could you do same test with m3 driver please
Would love to see how a longer shaft performs, my cobra is 2 1/2 inch shorter than my old ping.
Interesting that most of the comments say very interesting 🤔
can you give your take on position of weights(lead) on clubhead. Offcourse nobody put the weights on top of the driver head. It disturb the appearance. As for me I dont mind.
But is it legal?
Is any studies done?….weight on bottom or back is common, how bout weight on top? Will ball trajectory be influenced?
Based on your numbers with various tests of the driver, your peak height and launch angles tend to be super low. If you could consistently launch over 12 degrees you'd be hitting bombs. Maybe loft up? Consistently bottom and necky your strike would benefit from a set up where you start with the ball toe side of the aiming mark on the club head and let the club come back to centre. When you start centre you finish inside because the club path is traveling away from the body at impact.
Thanks, this is a very nice experiment! So too light a clubhead may cost loss in the smash factor – higher clubhead speed but lower ball speed. I wonder, then, what the best approximation method would be to lighten the club head to the threshold so to increase clubhead speed and maintain the smash factor in the same time – so ball speed can only go up.
Will it be 4 or 6 or 8 grams lighter in the head? Do we need a robot and computer for that? So and so, maybe all the manufacturers have figured that out long ago, no?
Does Cobra give you a package of different weights to play around with ?? e.g. 2-4-6-8-10-12-14-16-18 grams
Hi Mike, when you say 2 gram weight. Surely the screw weighs more than that. Do you include the weight of the screws in this. Great video by the way 👍
Very interesting experiment. I was very curious about this.
Yes! Finally! Great video 🙂 It is simple physics that a lighter head will lower the smash factor.
Interesting. I bought this last week.. good to see options and how the club performs.
Wee bit disappointed in this video. James Robertson did a similar video a few days ago. Mike I love you channel you are better than this. Keep up the good work. Ps still gave you a like. Cheers
I've seen people put 2 red weights in, would be an interesting test, I take mine out today for the first time can't wait.. Edit: just played 18 holes good God this thing is AMAZING , straight BOMBS I am speechless absolutely incredible, I am in love
Great video Michael. This touches on the question I have with my TS3. Would love to see the opposite of this video and see what adding weight through heavier weights(4 to 6 grams) does to ball speed and smash factor. My guess is that a few grams heavier then standard weights would bring both up and then past that you'd see diminishing results.
I do not understand what is going on! Here are the facts so this search ends. First- Shafts used to be tested at 205 grams to designate flex & point of flex deflection. The new standard is 200 grams because the modern head is about 196 grams & adapter weight added to total weight 204-205 grams at standard shaft length 45.00 inches. What you are doing is changing shaft flex & dynamic loft. Because you are capable of swinging faster, you lowered spin & dynamic loft. if the person can only swing 100 mph at 204 & 195 nothing is gained except changing MOI. Now, I'll give you another perspective. I built a M-1 440 2017. The standard weight was 200 grams with adapter. The standard shaft was 45.50 inches. It had extremely low spin & the MOI was poor. I installed a 17 gram weight all the way forward, then I installed a 19 gram weight in the center track 3/4 of the way back. With no weight in the front track the total head weight was 206 grams with adapter. I installed a Fujikura Evol. 1 shaft, 661 at 44.34 inches. The swingweight is now D-3 to D-4. It is the most accurate driver I have with a boring flight with a lot of forward roll. I have 4 driver's M-3, G-400,M-1, & ST-180. There is a reason why Ping builds drivers to 205-208 total weight. their adapter is about 5 grams which is about 3 grams lighter than Taylormade, Callaway adapter being the heaviest of all. Their heads are the lightest of all.
Very interesting!
Hi,
Interested clip, great!
One thing to check for you,.
Lengten shaft with less weight on head on a 47 and
48 shaft on test next time
and hit longer!
What's the chance of doing a video on the ping 410 plus wieghts system..
Would love to see the results with extra weights added to see the difference
I have an 18 and a 6 weight in my f9. At 44.5 with a speeder 661tr it swings out at d8.5. I just ordered some more weights. My build came out a little heavy with five grams of hot melt added to the toe.
Did the exact same thing on my R9. Wanted to see what MWT could actually do.
With weights out, the strikes were ALL in the heel, meaning that the CoG changed towards the hosel. With 16 gr weight in the toe, strikes were ALL centered and perfect shots. And that's how it has stayed.
