So i was lacking some spin with my wedges so i replaced my 56.10 & 60.04 SM4 with the same in SM5. What i have found is i can no longer play full shots with the SM5 at anywhere near what i was hitting my SM4 for example my 56 was 105m on full shot no lucky to get 80m. Yes i know worn grooves will add distance but this is something completly different. It is very frustrating. Pitch shots are fine just full swings.
