Need some advise. I'm starting to experiment with spinnerbaits. The one thing I'm unsure of is swivels. What to look for, what to buy & what size. I only have1 mold, 1/4 & 3/8 C style Do-It Mold. I got .040 R wire & #5 colorado blade. I've been told a #2 size swivel. Would really like some input, the do's & dont's of spinnerbaits. Thank's
