6.1 95 16x18 vs 18x20

[Philipp Kohlscheriber #1]

I have been using the k factor 6.1 95 16x18 and love the plow through and stability but my slice is not where I would like it to be with this racquet and was wondering if the 18x20 was a better fit for my game. I'm a 4.0/4.5 who mainly hits flat buy sometimes with topspin and rely on my kick and slice serves but will hit flat first serve.
I'm 14 years old.

Hopefully you have figured this out by now, but a more dense string pattern is not going to give you more spin/slice. Open pattern should give more spin. Stick with the 16x18 and maybe try a different string with more bite or different tension. I hit pretty flat, but get good spin with this racket when I need it.
