Nat Nat, do you mean the TT Score shaft (that is Maltby's go to iron shaft)?
I've found the Nippon shafts to be the best feeling steel, so you may be out of steel options. It has been about 10 years since I played steel regularly though, so I may have to consider that. Although I do have a couple dozen new graphite irons shafts in the garage dangit.
TS2 v. STi2: The STi2 performance is very similar. I'd have a hard time justifying the $30 difference on performance alone. The TS2 feels a little better. The TS2 looks a lot better. The one physical difference I would note is that the COG on the STi2 is much lower than the TS2.
