Every player is different and every player hitting different clubs can get different spin numbers that may or may not be what you would expect. In theory I believe you would spin the TS1-IM less, but that might not be the case. In testing, there was no noticeable spin difference between the two that I noticed. Again, every player is different. Spin is difficult to validate even with today’s best launch monitors. Small variances are considered insignificant. Only way to know for sure is to test against each other with same spec clubs and ball, and not sure that is something you want to do. Loft is the biggest factor and the lofts are similar, although the TS1-IM has slightly more loft on the 5,6,and 7 irons only. So, kind of a toss-up without testing. If I had to guess, I would say the TS1-IM would be more likely to spin less, everything else being equal.
