Personally I do not like any of these new Adjusting and Flex Trees that Tucker Makes and Several other people Make. They do not Flex to fit various size Horses as some places insinuate, some of these adjustable western trees also have reports of pressure points. They also have a weight limit or as I call it a bounce limit, come down on the seat to hard and the tree can flex so as to pinch your Horse.
