Line strength to diameter rating. I want to start throwing spinnerbaits on fluorocarbon this season instead of the braid I normally use. I figured 15# test would be plenty for throwing around the usual stuff nothing too crazy where I fish. Anyway, I noticed that on the package it states it is 15# with the same diameter as 12# mono. Will I be ok using this line for spinnerbaits or should I beef up my # test and find a different use for it? As always thanks guys.
