I started shooting limited division with a couple CTS’ from CZ Custom and have been shooting a couple of TSOs for the last year. After cracking a slide on one of my CTS’, I made it a point to try and be as competitive as I could be with the TSOs with minimal modifications. Even though I have never competed with a 2011 platform, I do not feel the TS platforms have held me back. I win local matches and have placed well at major matches, to include winning last years Idaho Sectional, and am only getting better with them.
If the TS platforms work for you ergonomically, I say be different and hunt the 2011s. If you like being able to change a bunch of parts to make something work better for you, the 2011 might be your best option.
