Go TTS. Half size up would be too big. I'm a 9.5 as well and the WC3 fit perfect in a 9.5. I hit a size 10 on the shock drop and they are too big. Going to sell them to a homie for retail and get a 9.5.
Pair came in from finish line. Was wearing my retro 88s today and man I'm thankful for how much nicer 3s are made compared to a decade ago. I'd say for me personally they are a little snugger then the reimagined 3s but not enough to go up a size personally.
