Line choice for casting jigs.

[keithdog]

I had a discussion with Kory recently regarding line choice for "CASTING" jigs. NOT PITCHING. Pitching jigs is reserved mainly for pin point presentation in heavier cover. I'm instead, talking about casting jigs in areas of less heavy cover, such as in gravel beds, points, submerged humps and so forth.
The way I see it, one won't need as heavy a line as for pitching. Various factors come into play I'm sure. But on "average", what's your choice in a casting line for jig fishing? Minimal line stretch would be important no doubt, but what about line strength? Would you prefer something in the 15 or 17 or even 20 pound size? Flourocarbon, mono or braid? Each has advantages and disadvantages.
I happen to have a brand new spool of Pline Flouroclear in 15 pound test, so I am going to use that for now. I love Flouroclear line for many reasons. Kory said he likes Segar AbrazX in 15 pound test. What's your choice and why?
