I am thinking about utilizing braid on upper half of my spool, and mono on the lower half in order to save money and not having to spool my entire spool with braid. Thus, I have to ask, how do you transition from the mono to the braided line? 1. Do you have to use the same equivalent diameter line in mono as you do in braided? For example, Power Pro 80lb braided is .0169" dia. And equivalent to 18 lb (mono?) (.43 dia?)? Does that mean i have to use 18 lb mono on the lower half of my spool as a filler? I would prefer to use 50 lb Fluorocarbon, but it's .028" dia.
