I have compared the same 18x20 medium flex 95" setup as 1) 358 g, 32.45 cm, 370sw, and 2) 375 g, 31.7 cm, 370 sw
1) served with more velocity, had less depth control on volleys, generated less spin, and was less arm friendly.
2) was the opposite. It had slightly slower, spinnier serves, better depth control on volleys, generated more spin in every department, and was more arm friendly.
The slightly slower serves were worth the tradeoff to me as all other areas of the racquet's performance improved.
