What species, what water type/size (ponds, lakes, small streams, big rivers, etc.)? Without knowing the specifics, I'd probably recommend a 9' #7. That would cover Smallmouth and most Largemouth (except for heavy cover & really big bass bugs). It would be doable but light for Pike, and would be a good match for most Carp fishing. If you were only going to do Smallmouth, Carp and Panfish/Sunfish, a #6 would be fine as long as you weren't going to throw really big flies. If Largemouth and Pike are going to be your main quarry, a #8 would be my first choice, mainly to help you throw bigger, more wind resistant flies. The Sage Xi2 is one of the best rods in the eight weight, and the Z-Axis is excellent in the #6 & #7. If you want a "budget" rod in any of those weights, the Temple Fork TiCr is superb- I own the 7 weight in that and I love it.
