i recently pulled my 08 moab out of the case to do some shooting. i drew back without an arrow with my release on, and when i let off, the string came right off the top wheel and stuck between the axel and the limb. this of course wrecked the string so i ordered new zebra string and cables and had them installed. ive heard about deep idler wheels available...any truth to this? unfortuneately ive lost my damn receipt sometime lately aswell. i was just wondering if there was any other such issues with this bow? also, is there any way i can register my bow without the receipt incase anything in the future happens?
