It all depends on what you are doing with them. I have found the seats in some of them to be more comfortable than alot of the big, wide ropers out there. They tend to get brittle with age though, and are subject to temperature change. They either fit a horse or they don't. The best thing about them is they make several specialty trees that are hard to find. It's also relatively inexpensive to replace them when they do break since they have never changed the patterns. There are several knock offs of these trees out there as well, and they are WAY worse then the originals. We used to build a production saddle for Weaver Leather a few years ago. We built around 1,000 saddles on the Ralide trees. We use a stainless steel pan head sheet metal screw on them with great success. The screw melts right into the plastic as you run it in. Now after that screw has been taken out a few times for repairs and such, you may need to retap it or use a longer screw. Also, the only time we have seen the bars tails broken off is when they have had string holes drilled all the way through them. They can and do hold up to several years of riding, but you have to have the type of tree for the activity you have chosen. A barrel/pleasure tree was not designed to rope out of for instance, you just can't get that through some peoples heads
