Hi,
I bought both these racquets and think will play in the future with the 95. For a few reasons: it doens't hurt my arm at all (much better under this point of view than the HPS6.1) and forgives when you don't hit a perfect shot.
The 90 on the other hand is more precise and you may hit very nice shots but I expect to have problems to my arm in the long term; then you have to hit the ball very well each time else your stroke is not a good one.
I strung the 90 at 52 lbs. and the 95 at 55 with Prince Original Syngut. I feel I have to better adjust this, in fact I would like to try with a lower tension for the 90 and with a higher for the 95, as it is whippy if you don't give topspin to each stroke.
This is my idea, but I have these racquets just since 2 weeks.
