Well it is complicated. If you were to want a versatile setup for summers I think a Skagit with Poly would be what you want. This is because you can dredge with T14 and huge leeches, which kills sometimes in the summer, or use the floating Poly and skate dries. But.........a Skagit line splashes a lot. In some conditions even when it lands 15' from the tip of a poly leader that is still too close. Especially for high pressure areas in low water. The fish have to be unaware of you in every way. So, if you want the best presentation, my experience has pretty much been narrowed down to the Elixer line. I pimp this line a lot, like no other really. I have never cast a line with such a long and amazingly smooth taper like that. It simply lands like NOTHING. Even if I use WAAAAY too big of a fly for this line, like a MOAL, and really pop my cast so it unrolls properly, the fly splashes and the Elixer will melt into the water. It is just delicate as all hell and I really love it for this. Big draw back to the Elixer though is a good breeze. Works better on medium to small rivers. I was wasting a lot of energy and deduced it was not worth it trying to use it on a breezy day on the Skagit. If I were you I would get both. That is what I did.
