Gee, how tall are you? Lots of the great cutters are less than 14'2, with big guys on them. My favorite horse right now is a Big Step horse, just makes 14, and let me tell you I feel very well mounted on her, and I'm not little.

Oh... and another nice ride (and there is a lot of prejudice against them, but thats for another thread) is a good old fashioned appy.
