Although I've never had a problem with any of the three Vipers that I own, it's good to hear if there was trouble Summit will stand behind their product!
This thread scares the you know what out of me! I switched to summit about 3 years ago after we had two grand slams pop. No one got hurt but sure turned me against the grandslam. Guess I'm gona break out the old aluminum spool gun . Go back to the old days and build my own.
