Because the horse's back is in constant motion this is why a rigid tree works altho a rawhide covered wood tree has a bit of flex whereas the Ralide doesn't. A flex tree, depending on maker, can cause a horse problems because of how it flexes. The early ones were disastrous ie if it lifted here it pushed into the horse there, creating a sore back. Also there were weight restrictions. There are also "flex" trees that are merely closed cell foam between the tree and the skirts which adds a small amount of flex in the broadest sense of the word. A friend is dropping off her Passier AP, a gift, altho I suspect it's not wide enough for my boy. I haven't seen it in 3 yrs so memory may not be correct. It was an awesome saddle to ride in, felt custom made.
Southern, I'll check out those links. Thanks
