She's such a cute horse! Sorry to hear you're back to saddle shopping. It's miserable if you're in a rural area and/or there's something vaguely non-standard about you or your horse. How I envy average sized people with average sized horses.
If you ever get to the point of getting a new saddle, Custom Saddlery is awesome. They will make something that fits both you and your horse, and they do more than just shorten the flap for a short rider.
Also, many nice saddles, like possibly that Albion, are adjustable up or down at least one tree size, and possibly two as long as the channel is wide enough and the fit is otherwise good. Anyway, I wish you a short and successful saddle hunt!!
