I've ridden in a couple of Innovas and they are by far the saddle that puts me in the best position with the best and strongest lower leg. I haven't found anything that sits me nearly as well. BUT... they don't have a lot of wither clearance.
Magic's withers aren't huge but the only saddle I've ever put on her that DIDN'T want to sit down on them is her Kieffer Wien. It's a lovely saddle but she's starting to grow out rather than just up and it no longer fits her as well as it did... and it sits me well but not as well as the Innova.
A big plus for the Innova is the easy-change gullet system. But has anyone had luck with them on higher-withered TBs? If I used the shim system could I pad it up so that it gave sufficient clearance, WITHOUT losing feel on her back?
