I consider my "for fun" racquet as more of a training racquet. I use either a weighted up Blx 95 2011 or a 2012 Blx 95. Since they are both heavier, my usual racquet feels lighter when I switch back. I also hit with an Aero pro drive gt once in a while. Other racquets I hit with less often are: K90, ps85, Hps95, K95 and Hps tour 90. I also use the other racquets to test out strings.
