Honestly I liked the STi2 PW and GW just as much as the TS1. But then again, I think I only had 2 hits with each. But yeah, I think the STi2/TS1 mix could work well.
Man, I wish I had a list of all the graphite iron shafts I have tried...Matrix Kujoh 95, Wishon Interflexx, Kuro Kage 80, SK Fiber Tour Trac 95, Recoil 110, Recoil 680, Recoil 660, SteelFiber 115, Project X PXv, Fuji Pro 95, Miyazaki Jinsoku 78.
My TS1s have a set of old UST Tour Weight graphite shafts - 110-114 grams. Those shafts have been in several set of heads for me, they are so good. The new Aldila 85s really worked for me today, and I have not had much success with <100 gram shafts.
