Pros: ligher rings and straps, good shocks
The tower in the picture is a single tower(meaning the actual tower is made up of only one beam) but international models have two welded beams, which is more stable. The rings are fiberglass and the straps are fabric which allow for a lighter ring set, which I like a lot. Also the shocks at the top of the rings are the best out there and make it easier on your shoulders as you swing through the bottom. I have competed on many different ring towers, and these are by far my favorite.
