I think hard polished stainless is the best. Carbon fiber is probably the worst, so if you use it, you could be a boob. I've had both Myers rods and Ivy rods and Ivy rods are just as good and may be better. So, that's what I would, and do, go with. I have one with an integral jag and one with a screw in jag, and generally use the latter.
That's my opinion and that's all it is. I used to use the Bore Tech and Dewey coated rods, and personally never had a problem with them. I think the potential for problems is greater, but at the same time, you can't be a dunce and expect everything to go okay.
