I love my thin beamed K90's and have used all the other Wilson 90's as well. I've lost count of the many times I've tried to switch to a larger frame but have always returned to my 90 or PS88. Can the 90 users who have made the switch give details of their process and what larger frame they are now happy with? Thanks. I've purchased and sold the following: Prestige, Rad Pro, IG Rad Pro, IG Extreme Pro, APD (2009 and 2013), Dunlop 300, EXO3, Becker Legend, BLX Pro Open.
