I have a HC carbon 4 runner that feels like nothing else. Purchased it last year and had my stabilzer threads strip out. I e-mailed the mfg and they were going to send me free inserts but I had already used heli-coil to fix the problem since the season was starting in a couple days. I love my bow but having trouble not trying out the Mathews LX, even if I get the Mathews I' ll never part with the 4 runner.
