Been playing with the 2017 version of this frame with full poly from 45-47. Interested in using a poly/ multi or poly/syn gut hybrid to generate more power and mainly create a bit more feel. Considering Max Power 1.25/ NXT 1.30 or Luxilon Alu Power/ NXT 1.30. Any strings you guys could suggest for this 18x20 frame and what tension would you use. My guess is between 50-55 just not sure.
