I've hit the r7 425 a few times and liked it alot, but a friend said I would do better with a larger headed driver as it will be more forgiving. Then someone else told me that because of the weights, it has an MOI similar to other regular shaped drivers, (not the square or long headed drivers) and is therefore just as forgiving.

who is right?

Me personally, I had an R7 425 clone that I liked alot. Then I got an R7 460, that I could not hit over 250 yards to save my life. Now I am using an R7 Quad which is only 400cc. Frankly The big head concept dosen't work, I hit drives in the 400-425cc range better than I do the big drivers. Maybe it is a mental thing.

The MOI of the square drivers are indeed higher than anything that has been made manufacturered in the last few years. There were actually some small component makers of square drivers in the late '80s. But, the square drivers have the highers MOI of anything made by the big OEMs, including the moveable weight drivers.

However, there is a law of diminishing returns when it comes to MOI. The jump from 2,000 to 3,000 (g-cm^2) was very signifcant. This was the Big Bertha era. But the jump from 3,000 to 4,000, which would be around years 2001-2002ish wasn't nearly as significant. Last year's 460cc models were around 4,300. The square models haven't quite gotten to 5,000 yet. But, the increase at this point does not really add significany playability. The manufacturer's love to claim how much better they are, but the actual facts are that as regarding the playability of the club, it isn't too big of a deal. The limit the USGA set is 5,900, but again, because of the diminishing returns, there may actually never be a driver made to the max. It just won't improve the situation that much.

Rather, you should play the driver you are most consistent with, the one you like the best. There aren't really going to be much improvement in terms of forgiveness unless the USGA changes the rules.

Thanks for the comments. That backs up what i found today. I tried the superquad and the 425 at the range today and much prefered the 425! Custom fitting fit me up for regular flex and 10.5 degree. "Oh we have a 2nd hand one of those out the back" the guy said, so I now have a nearly new 425 at a great price
