Do you have an opportunity to hold them and see how they feel in your hand? I've got a TSO, Shadow 2 OR and very well tuned SP01 with CGW bits and pieces among other CZs. The TSO and SP01 share the same frame/grip geometry. The Shadow's geometry is different with more of an undercut under the beaver tail and finger guard. I don't own a TS2 yet (but dang, I want one!) but it looks like it has adopted the S2 frame/grip geometry. I admit I prefer the S2's geometry over the TSO and SP01 but it's a personal thing that's gonna be different for everyone. I will say tho that my TSO is the CZ I'm most accurate with and the best built CZ I own, with an amazing trigger that's almost too light. I've got a frame mounted optics plate and SRO on mine. It's an absolute joy to shoot. I can't wait to try a TS2. They seem to adopt the best of all features taken from the TSO and S2 series of CZs. If you can't handle all 3 before you buy, I'd say go with a TS2 green. Can't see how you could go wrong.
