Hi, Grubb!
In addition to the maker and his/her attention to the craft, its certainly the taper you are after. With cane as with everything, "different strokes for different folks". I'm with Harry... if we knew where you are (roughly) we could maybe direct you to some good hands-on opportunities. Here in Maine, we get together with cane for a morning in a gym in February to fight cabin fever and to share rods of all sorts. Some FAOL people came last year (Mer, hope to see you again!).
I'd also recommend trying different lines if you can. I love my rod with a 5wt, David (husband) likes it with a 4-wt.
There are excellent rods around for $800. There is also a good chance you'll have to wait for rods from some makers. Its worth it to invest a little more time, like you are, investigating rods first.
If we knew the waters you like to fish, we might be able to suggest some tapers.. at any rate, your rod maker will be able to give you ideas.
