Spinners were my first love as far as bass fishing; and my biggest Delta fish, scaling in at 8-3, was caught on a spinner bait. After my jig molds, the banana spinner was my first acquisition for auxiliary baits... I have several others now, but the banana will always be my favorite because of it's multiple features. It is just so versatile that it I highly recommend it, especially for the person that is trying to keep a lower inventory of "stuff" from getting out of hand. I have made and continue to make both spinners and buzzers from this same mold. (I now use the buzz-keel for my bass buzzers, but I still use the banana for my musky buzzers because of the heavier weight option.) The only modification I would recommend to this mold is to drill out the wire groove to .043.
My spinners aren't works of art like the ones you see posted here (because they are for personal use only, and I know the fish under my boat aren't so snobbish that they will hold out for one with more bling). The biggest thing, as you likely already know, is personal confidence... after that, it gets to be a matter of changing blades, skirt colors, trailers, etc. with the conditions... so just get dirty with it!
