Hi guys!!! Well, after 4 or 5 hybrid jobs (polys on the mains and multy/syn gut on crosses) I've decide just for fun to try out a full poly job on my 102 sq. inch head. I got some half sets left to string my racquet, i want to use SPPP (1.23mm) for the mains and TPCF (16) for the crosses but I not sure what tension to use. I was thinking either 58/56 or 56/58 being that the RST is 57 +-5 and using the 5%-10% less tension theory. Can you please help? Any advice would be appreciated! Thanks to all!!!
