My own opinion is this. I find a lure I like, trace around it, cut out a piece of balsa, sand it down, add a lip and weght, coat it and test it in the bath tub. I know this hobby can get very technical, and people are doing and building some amzing lures here on TU. But to build a normal 2" crank its pretty easy. Swimbaits, are totally different, it seems you need to be a rocket scientist to build one of those. JMHO
