Hi i recently want to purchase either a used wilson prostaff 85 or a wilson prostaff tour 90 and i'm not sure which one to get. I have hit with the china wilson ps85 and i really liked it but i'm afraid it'd be a little demanding for my game. I think i would judge myself as a 3.5 right now and i would like more demanding rackets to help me improve on my shots. I am currently using 2 200g's weighted up to around 13 oz and i feel like i could hit fine with the wilson prostaff 85. So can anyone offer insights on either racket? thanks!
