im 38 and prefer to ride the smaller ones. got on my daughters 16 hander when we first got him and thought i am way to far from the ground ! lol. i have been known to jump on our 13.3 welsh when shes being a prat and must look rediculous to boot ! i dont tend to ride much nowadays though but would like to get myself a horse eventually seeing as i do most of the work and the kids get most of the pleasure! otto was originally bought for my daughter and i to share but he is a one person horse so i dont bother riding him! i think if and when i get myself one it wont be a biggun!
