Looking for two-piece string pattern (instructions) for this model. Wilson and Klipper do not show the model at all. TW site has it only as One piece, 16 Mains / 19 Crosses, Mains skip: 8T,7H,9H, No Shared Holes, 50-60 pounds. I have been stringing for years, but always as two strings. Any advice how I can do this? Thanks in advance.
