My Sage RPLX 990-3 is about perfect if I could only have one. Plenty of backbone for hauling fish out of cover. Handles 11wt shooting heads and 30ft of LC-13 for fishing deep or casting huge flies. I have a number of other rods in 5-9wt from Sage, Orvis, Redington, Fly Logic, an Winston but the RPLX is my favorite.

If I had to replace it, that would be a Sage Xi2 of same size.
