At the moment, my all around stick is my Sage XP 9 1/2' #5. It's a great nymph rod, and it will toss streamers no prob, and the extra length softens the tip enough to fish dries and cushion the tippet. I mostly nymph though, so I lean toward a slightly longer rod, often a 10' #5. For Joe average, a 9 footer might be the rod, prob in a #5, or maybe a #6 if it has a more moderate action like a Sage SLT or a Winston BIIx. Strol-Eye loves his 9 1/2' #6 Winston BIIx, even tosses small dries on it sometimes. It works great with streamers, and is beautiful for throwing yarn and double nymph rigs. I cannot wait to get a new Sage Z-Axis, I think they are the nicest series of rods I've ever seen. Another rule of thumb for me when picking the rod of the day is time of year and water level. March & April are really windy on the Housy, so I often nymph with my #6 XP. Higher water also dictates bigger flies and heavier tippets, so again I'll go heavier under those conditions. Conversely when I'm fishing in the Summer on the Farmington, I'll use a 9-10' #4 as my all around stick- wind isn't a problem, and I'm often fishing smaller flies and a little bit lighter tippets(although not as light as most other- rarely below 6x, usually heavier), often fishing in shallow water too. The 4 weight gives me a little more delicate presentation, and I think maybe it's a little easier to get a drag free float (the line is thinner & more supple, so it affects my leader less during the drift).
