I have broken a blade on a prop, had my spare with me, changed it out and won a tournament (now thats a rarity)because I had a spare with me. We run long distances down here and its just too easy to carry a spare prop. If I fished smaller waters I may reconsider but for fisheries where it is common to run 100 miles in the course of a fishing trip it is a must have! Downriver in Venice it may be the difference between coming home or spending the night tied up to a buoy marker. Just my opinion.Chris Coupel Paulina, La.Chris CoupelPaulina, La.
