12# Seaguar InvizX is a line I would consider throwing it on, the reason being is, Seaguar InvizX has significant stretch for being a floro, most people like SOME stretch when throwing a spinnerbait. Plus InvizX is a super soft, supple, low memory floro, although invisx sucks for bottom contact fishing, I love cranking with it. I personally use 12# P-Line 100% floro, because when I spinnerbait fish I'm up close and personal in buck brush, laydowns, and stumps, so I need minimal stretch, I'm also a guy who does ALOT of slow rolling, 95% of the time I'm spinnerbait fishing I'm slow rolling it. If you like to slow roll spinnerbaits I'd go with P line 100%, but if you burn them, or just use a steady retrieve pick up some invizx!
