There are sage One rods on clearance all over the place! I got a 9' 5 wt for $475 and I'm SOOOO happy with it.
My local shop still has them for $475 and free shipping! Sage One, New, Clearance From $475 - Upcountry Sportfishing
It's just about impossible to get one rod to do all things well. A fast-action rod does not drop tiny dries very delicately on the water, and a good small dry rod doesn't really have the action to throw large streamers and such across a large river. You can go with a medium action which does both sorta OK, but still not the best for either application. That's why most fly fisherman have multiple rods. I prefer fishing large rivers with large flies so most of my setups are fast-action, but I do have a 3wt light action for packing in and laying down small dries.
