I was wondering if there’s any difference in groove width, depth or volume between the TS-1 irons and the non-hollow irons like the PTM or TE one-piece forgings?

The reason for my question is it’s been my observation that hollow irons with the thinner faces have somewhat shallower grooves and are more susceptible to fliers out of rough or wet turf. So was wondering if that would be the case with the TS-1’s as well, or whether my hypothesis is bunk.
