My gelding is a draft cross, probably clyde and he is a wonderful trail horse although I agree that at 17.3 you don't have as much overhead clearance and if you get off or have an unexpected dismount, it is harder to get back on. He is very nimble, brave and strong, really enjoys it, often he behaves better than the other rider's horses although he is only 4 yrs. old, no goofy, tempermental behavior, always the same horse you rode the last time. Depends on the horse too, but he has a great, ground covering walk, smooth jog and trot. Haven't gotten to cantering on trails yet!
