Hello! I am looking to get a new saddle for my horse, and am pondering on the apropriate seat depth. I am a thin, long-legged rider (long-thighed, actually lol) and will be eventing (so I need to be able to comfortably do all 3 stages). I've heard that the deeper seat provides a good deal more security (and usually more comfort :) ), but also that a deep seat is harder to "get out of" to jump, especially cross-country. Usually a flat-seated saddle is close-contact, right? Any comments on those? I'd love to hear feedback from any riders out there!
Just for reference, two saddles I am especially interested in are a lightly used Beval Devon 2000 (a close-contact saddle), and a lightly used Stubben Scandica Nova (a CS, or half-deep seat saddle, also more close-contacted). That's why I ask...I'm wondering which will provide the more exact amount of security and balance for me.
