DO they have similar characteristics give same strings and tension.? I'm wondering cuz I'm thinking of buying one...from sg
The iso 500 has a solid feel to it, while the iso 900 has a quick maneuvable feel to it. They pretty much feel the same nonetheless unless you really are very picky concerning characteristics.
Well the 500 is about the same as 900(with slimmer shaft). When comparing it with the Ti SP, it should be a bit stronger on impact with the titanium at the head, plus the racket is a bit stiffer than 900/500 which increases the power as well. I use to have 900 SA and SR and now swtiched to Ti SA and SS. Both work great but I prefer SA better because of the speed. Also my arm power is not strong so I use speed to generate the power.
