I had a lesson once on a 17.2 Clydie x TB, called Dallas. Lovely big beast, but he would insist on using me as a scratching post!
I also went to a riding school for a while where the instructor had a stunning Clydie x TB called Billy. He was about 17hh, and I went utterly daft for him! I practically begged her for a whole year to let me have a go of him.... which she finally did! Responsive and forward-going, able to turn on a sixpence, but quite a sensible horse, too. More like a slimmed down Clydesdale.
I also went to try out a Clyde x TB mare a couple of years back, but it didn't work out. Something about her just didn't quite ring true.
I'll look out photos of all three if anyone's interested...
