that's what I would say...
I am 5'10 and weigh in at 240. My tack it probably another 50 (heavy saddle...), and my little 14.2/14.3 app gelding has no problems with me, and we've done some significant workouts. We taped him last fall at just under 1000 lbs.
I also have spent plenty of time on my wife's 15.1ish gelding (20+ years old), weighs less than chief does, and I spent every saturday last winter on him up north in the snow. Done some hefty workouts on him, too, and he never had any problems.
Also been on my wife's TB numerous times, never any SERIOUS work, but enough to make him sweat. It don't bother him none, he's over 1100lbs, 16.1 and WAY too energetic.
Anyhow... I find 14.2-15.0 to be just about RIGHT for me. I really don't like more than 15.2. The TB around here is too tall for my personal preferences. But YMMV.
