I would string it as an ATW pattern string 36’ with 8.75’ ss. Tie off the short side on the short side.I just got the racket in hand and it is strung exactly according to the pattern you suggested. It is 16 x 19 is the only difference. Two piece. Any suggestions on length of string to use on mains v. crosses? I never trust my judgment without stringing instructions.
Good plan if you use a starting knot for the top cross and have a starting clamp for the bottom cross just in case. If I was stringing with poly I would still use 36’ with a 9’ 6” short side (don’t start with 2 pieces.) What you cut off the long side will be around 18’ and more than enough for the crosses.I would string it 2 pc. 19 x 17 should be plenty even with poly.
