RECOIL SNAKE GUIDES - with PRE-TAPERED guide feet. Sizes 2/0 thru 6: Recoil guides are made from an extremely hard but flexible "Shape Memory" Nickel Titanium alloy. Recoil guides instantly return to their original shape if mashed, are 60-70% lighter than conventional snake guides and cannot corrode in any environment. Because they flex with the rod, there are no flat spots, creating higher line speed.
