Ed, Of course you know that I've made a lot of long drivers for seniors' golf course play here in Tellico Village and around my home area. So, I just want to express another personal opinion that, yes, there can be a performance problem with square heads when used on long drivers (47" and 48"). By moving many ccs to the rear left and right, the face is shallower than most round-shaped 450cc-460cc heads. My Quad driver face is almost "rectangular" (long and not as high) and combined with a bit more upright lie which puts the toe up a fair amount at 47" and me at 5' 9" tall, makes for a very small, angled impact area. Even with a correctly aligned shaft at my preferred differential deflection, my near center impact consistency is less than with my more round BOM 460cc head. And, especially a fade swing with the square head doesn't go near as far for me as a straight or draw swing...unlike my BOM, which hits a fade swing ball almost as far as a draw swing ball. So, though I think the square head plays very well at normal lengths, its shape combined with an upright lie can hurt the square head's performance on a long driver. With a lie around 55° (a guess without checking) instead of the "near 60°" on the Quad, it might be a lot better for longer clubs...wish someone would offer one those at 195 grams. I hit the Quad very long for me, when I hit it on center.
Someone on a golf forum mentioned that Tiger wouldn't play a square-shaped Sumo, because he couldn't work the ball with it very well. Seems to me that's a performance problem for some players, too. Would any high MOI 460cc head give him the same problem? Comments?

I simply said that Bernie reported poor performance with a square fairway wood. I've never hit a Quadratic. My only point was that the shape of a clubhead, in and of itself, is not a key performance factor. /Ed
