I took my set of TS4 out today to compare against my normal set of TS3. I am not sure if I was having a good iron striking day or what, but I found better consistency with the TS4s today. After some swing changes last year, my miss with the TS3 has been left. The TS4 for whatever reason doesn't miss left, or as far left, like the TS3 do for me. I'll keep using the TS4 to see if this trend continues.
