Yeah, any rubber you can't serve heavy spin with, no matter the reason, will be relatively hard to play with.User error
Seriously though, because of the stiff topsheet I had a hard time generating spin at low and medium power. This led me to just flat-hit whacking the ball when it came to my FH. Also, I didn't get good spin out of my serves. I'm guessing a lot of the problems were due to my low level, but I didn't want to develop bad habits.
