It will be at its best with typical tapers of the 'glass era in standard weight lines. These lines were made for that type of rod, and it is a good one. It is not an especially light blank, which in 8' yields a very comfortable rod with self-loading capability, and thus versatility in line weight. The sweet spot will be DT6 or WF6, or maybe WF7 with compact, short backcast. I use mine with all of those, plus DT5. Try a conventional WF6 first. You don't need to hold your tongue a certain way to have this rod perform well, and it doesn't need a specialty line; if anything, an unusual weight profile will narrow its capability with little to no gain in that one type of casting/fishing.
Here's a good older discussion about lines that suit 'glass rods (I think it's the one from the time when the 406 fly line products were being planned). The discussion emphasizes DT, but WF in standard profile and weight is covered as well.
viewtopic.php?f=36&t=46792&p=190409&hilit=on+the+market#p190409 Other brands--read the product description as to weight and profile--also offer what I have been calling "conventional" or "traditional" or "standard" tapers/weights.
Here are two 8' Conolons (refinished slightly differently) that I used fast and furious for a few seasons. I often rigged one with a WF6 or 7 and the other with a DT5. Here, with a Cortland WF6 fast-sink tip.
