mreklaw - 2017-02-09 11:48 AM I have ridden 2,3 &4 year olds with a treeless. The only ones I don't like to ride are the ones that may still want to buck a little. Also, I usually ride with a saddleright pad. It's not real thick but offers a lot of support for their back. If your horse doesn't have much withers then you may have to use a thinner felt pad. I like the Bob Marshall and the Jackie's the best.
