Nat I heard the ts1s were about as forgiving as the ts2s. Not your experience?
I'm my experience (had both), the TS1s are around 97%-98% as forgiving as the TS2. I never had any problems with the TS1 long irons, they were plenty forgiving for me. I would not base a decision trying to compare performance of the TS1/TS2, they are too close. Pick by looks, loft, sole, how it tastes when you lick the face, then maybe forgiveness.
