I am currently playing with SPPP 1.18/ Nxt Max 16 at 54/60 on a Wilson NTour. Am looking to venture towards a full poly setup. How much lower should I string it for a full poly setup compared to the 54/60 hybrid above. Also I saw some really great reviews at String forum for the Proline II strings. How do these strings compare to SPPP ? Are they noticeably softer than SPPP ? I love the amount of spin and control I get from SPPP. The only minor gripes are the slightly decreased feel and boardy feeling with a fresh set. Thanks for your responses folks.
