Joey:
The organic clutches allow some degree of slip if you really do a hard launch but will recover when they cool down. That way you do not get the instant shock loading transferred into the gears.
I would rather some small slip with a bit more clamping force than stripping 2nd gear and doing a gearbox re-build.
05wgn:
The gears found in your gearbox used to be considered a desirable upgrade for pre 02 WRX's because of the widened 1st-3rd gear teeth. These previosuly were only found on the 97 onwards JDM STi R & RA's and I think the 99/00 Oz STi's. The 4.444 gearbox final drive ratio also helps.
Not a lot of people are stripping 2nd or 3rd gears these days in their 02-07 WRX gearboxes even with moderate power increases for these very reasons.
Here is another Exedy H/D Clutch Kit (FJK-7123HD) - $550
