I guess I should have answered the original question....
If you havent used the XPS Sig, Series of mono and flourocarbon you are missing out on some great lines. This year I used it exclusively and was very impressed with its strengh, abrasion resistance and sensitivity. It is a litle larger in diameter than other lines per pound test, but the advantages and price are well worth it. Heck 8 pound test will stop a bass boat like an anchor if you can tie a good knot.
I used to use Berkley Trilene XT exclusively, and still do when needed, for most of my baitcasting AND spinning gear. The XPS mono is very similar in characteristics, but I would say that XPS is a little "softer" line.
As with almost all fishing lines, you should use a line dressing (Reel Magic, 100% silicon works too, no silicon valley jokes fellas). Just spray it on the line in the morning before you head out to your first spot. It helps "relax" the line, making it more managable. Especially true for flourocarbon line and heavier mono, but I use it on all my line with the exception of braid.
More tips for flourcarbon:
1. On spinning gear is to use as large of a diameter spool as possible, even if it means to "oversize" your reel. I am sure most of you use "2000" series spinning reels. I like to use "4000" series reels because of the large diameter of the spool. Flourocarbon doesnt like to be "wound" up and it wont be as much with a bigger reel. The added bonuses are longer casts with all lines, especially jerkbaits in the wind (hint hint Rob).
2. Flourocarbon line is actually more abrasion resistant than mono, but one little scratch in it and it likes to break. KEEP A CLOSE EYE ON THE LINE! If it starts to fray at all, even if you THINK it might be, retie. I use a Trilene knot with good success and know others that like the palomer. I do use a palomer when drop shotting.
3. I do not recommend that it be used with top water baits or any other bait that you would be concerned with the line sinking. Flourocarbon sinks and can be used to help your crankbaits run a little deeper when needed. It can also make a difference when using soft jerkbaits....(hint #2 Rob)
4. Flourocarbon line has its advantages too....much more sensitive and it virtually disappears in clear water. It has the same light refractive qualities of water and becomes difficult to detect in the clearest of water.
The stuff is more sensitive than mono and less than braid. Great advantage in working jigs (tubes, grubs, etc.) and slow finesse type presentations.
Try some or all of these Rob with some 10lb XPS Sig. Series Flourocarbon and I think you will see that it is very effective and can help put fish in the boat, especially on days that are tough in clear water.
As far as a C-Rig leader, I use mono. The flourocarbon sinks the bait in some instances. Mono will help float the bait off the bottom, but some days sinking might be the ticket.
