NO control problems for me on the 99s or my 105s so far. Played 3 sets yesterday and it is just about the same control as the Yonex frames I have played in the past few years. I am playing with a 17g MSV at 52# in the 99s and 54# in the 105s. However, i don't often take big long swings at the ball, I am glued as much as possible in doubles to 1-2' from the net, so yesterday I hit a small amount of strokes from back for 3 sets. I love the volley control on both frames right now.
I am actually finding more control right now in the 105s actually.....but I that will remain to be seen when string gets a little older in both frames.
