I hope this is not a misprint because wilsons site only has a 18 x 20.
I played with the K Pro Tour and loved it and was very disappointed when the announced the blx version to have a 18 x 20 pattern.
I just bought 2. <$150 final price including tax & shipping. Also both will be strung with 16g syn gut for free!!
Racquet: Wilson PS97 String: Prince syn gut @55lbs in mains, ISOSPEED Baseline Control 16 @50lbs in crosses, Wilson 6.1 95s backup same string setup
