12 1/4" strips of lead at 3 and 9 ought to finish the debate.

Shouldn't that be 1/4" lead tape?

I think, but not 100% sure, that you both are right. I think kiteboard is reffering to the total amount of strips of lead at 3 and 9. 3x4 sides would be 12 strips of lead, and the length could be what you have said. Not 100% sure though

He used 1/4" strips, each a little shorter than the last, 3 x 4 sides=12. 389 g total mass.

The PS85 and KPS 88 with 18mm or 17mm beam width are too thin for 1/2" lead tape to fit.

The specs at Gregg Raven's HD Tennis site for Sampras are 384 g, 32.1 cm, and 367 kg•cm^2. Assuming those are strung specs, that would give a polarization index (recoil weight divided by mass) of 0.467, which isn't remarkable either way for stock racquets (the average for the 1200+ racquets on the spreadsheet in front of me is 0.464) and is less polarized than almost all of the pro specs I've run across (the average for 17 ATP players at the 2009 BNP Paribas Open was 0.52).
If you use the specs from the 1993 ATP World Championship in Frankfurt (don't remember where I got them, but they are 390 g, 32.3 cm, 379 kg•cm^2), it comes to 0.475.

Well IIRC he didn't really mess with his balance and weight distribution, as he wanted it as close to his old Kramer as possible (correct?)
So it could be that those Greg Raven specs are indeed unstrung, as the 379 SW seems more likely considering how much lead he placed at 3 and 9. I myself tried the same amt of lead on my BLX90, and it felt more like 375+ than 367 (similar to how I had my Radical set up at the time)

I've seen figures that list it as 384-389g, in that range, and just try to serve and volley with that log, I dare you!

The weight of the frame is what's good about it. For serving, the added mass really shoves the ball. For volleying, you just place the frame out in front and block. The added mass and stability makes for a rock-solid volley. I'm convinced people arm the ball too much these days.
