I have had the same exact problem with screws coming out of my cams. just a little vibration that progresses. nothing that a little blue loc tite or even string wax in the threads won't repair. I also had the limbs crack on my 06' allegiance. Will I buy a bowtech when I'm ready for a new bow? YES. I firmly believe that the cracked limbs were due to personal error with my dealer and the allen screws are an extremely minor issue. their customer service is the best I've ever seen. You don't really see a whole lot of advertising from bowtech, so you've got to ask yourself the question, why do all these guys love bowtech so much? the answer is thousands of satisfied customers. I like to think of it as instead of putting all their money into advertising, bowtech is using that money to bring new innovative technology to the table for us.just my 2 cents.
