Wow, Rob. It seems like the line you fish is considerably heavier than mine for most applications. Is it just a major confidence booster for you? I really feel pretty comfortable with fishing lighter line than most folks do. Don't get me wrong, when it comes to the swimbait it's 25 pound mono and and hammered drags, but sometimes I guess I just don't see the light when it comes to fishing heavy line. I suppose if you can get away with it, go for it, right?
Crankbait- 12 pound Izorline XXX. I usually throw cranks around alot of pretty gnarly stuff trying to get the reaction bites from the bait bouncing around and it holds up well. I know some guys who won't throw a crank on anything under 15 pound. Go figure.
Jerkbait- 10 pound Izorline XXX, 8 pound Izorline XXX if I'm throwing Pointer 78's or smaller baits.
Jig- 15 pound Izorline XXX, 12 pound Izorline XXX if I think I can get away with it.
Flipping- ??? I really do not do a whole lot of flipping aside from the jig, being in SoCal and all. The lakes I fish really don't call for a whole lot of the 20 or 25 pound mono or 50 pound braid and a full on 7'6" or 8' rod like the Delta or Clear Lake. I really want to do that type of fishing but there really aren't too many situations where I can.
One thing I do recommend is trying out the Izorline XXX. Really strong line that has really low memory. Another user of this board got me to try it out and now I have a bunch of spools of the stuff in my room.
