Fought 150Lb+ YFT for 2 plus hours this weekend with OTI 7'6" popping rod. Covering over foregrip slipped down 2-3" and started to wrinkle at reel seat. I'm in Cabo and want to fish with it again but way uncomfortable. Rod is only a few weeks old as I bought it for this trip. Would I void warranty if I removed the wrinkled covering? Any other ideas? Really want to catch big YFT here with it, but cannot fight very long with grip as is. What to do?
