So the GPM's are the way to go. I added a washer to the stockers the other day, and put them to the test yesterday. I was jumping about 12ft up and 20ft out, and they never popped off once. I still think I'm gonna get the Ti GPM turnbuckles, just for the added strength. Some people say that the GPM's fit better with the stock ball joints instead of the ones that came with them.
