Have tried them both, a 315 in stock condition and a 295 with about 5-6 grams total at 3:00 and 9:00, the only counterbalance being two overgrips. (Have not tried a stock 295 -- have never used 11 ounces with much success -- but it felt alot more solid in the head bare than sticks like the Pro Open or Formula 100). I found the 315 personally to be a little sluggish, very solid and stable but too difficult to whip, especially on serve. Those less chronologically challenged might be just fine with the 315. The 295 weighted gives away very little to the 315 in terms of stability and plow, not enough to bother me; much easier to whip around in executing The Modern Game; both are extremely comfortable, among the very few racquets I found no need to use a dampener with. Certainly more pop than the Ki5 series.
