Thanks MAXXply!
But this is the problem: I'm looking for a Mag 90 not to play with, but only as a collector, and I would like to get the same racket Pat Cash used to win his Wimbledon. So, if the 90 and the 110 are very close in the oval dimension, this doesn't help me understanding what kind of racket it is without the exactly specifications of the 90 (or the 110). I've compared it with one Head Prestige 600, and the Mag was a little bit wider, and with an Head Elektra 660, and the Mag was surely shorter and tighter. So, maybe, it's a Mag 110, as it seems to stay between a midsize and a midplus (and you said "I always thought it looked and played like a 95sq.in.").
What do you think about?
