Kray,
I will repeat that I'm mostly a graphite guy. The bamboo is BETTER at certain tasks, at least IMO. It's not outdated, inferior, or anything like that. Not better at everything, but better at some things. And most of my rods are specialists anymore.
As for the OP,
Gfen is correct. Everything here is subjective. Guy #1 loves one rod and hates another. Guy #2 is the exact opposite. So it goes.
We describe actions as slow, medium, fast, stiff, or whatever. It's all overly subjective. One guy's fast is another's medium. It's also overly simplistic. Tapers are complex. We picture a typical progressive taper going from thicker (stiffer) to thinner (softer) from grip to tip. And that's basically true, but it's not a perfectly smooth taper and those details vary wildly. As do the materials and so forth.
The simple matter is that I can cast one "fast" action rod and hate it, and cast another and love it. Same with a slow action. "Feel" is ridiculously complicated to describe, but when you cast it, you know pretty quickly.
For me, well, I tend to overpower my casts, even at short distances. For dry flies, I don't "lay it down soft". Heck, I almost never try to straighten out a leader like that. My most typical cast is to throw a rocket of a cast aiming to straighten out with the fly about 4 ft above the water, then stop it with a shock, and let the line and leader fall down to the water in S-coils. I also sometimes do slack line casts or pile casts. When nymphing, I throw a lot of tuck casts. For big stuff, well, I just lob.
With my style, I basically like rockets. It should take all the power I wanna give it, and at least feel like it can take more. What I hate with a passion are those rods that feel like they have a "hinge" around the handle, and when you give it more power, it seems to just fall apart. Troutbum's fit the mold.
But you can get that power even in a slow or medium action! Like I said, I even like the bamboo!
I can respect wanting to splurge. It's not necessary, but it's fun. But you don't want to spend this kind of money without making sure you're gonna like what you get. And the only way to do that is to TRY IT OUT. Take 5 or 6 different models, go out to a lawn, and have at it. Any reputable fly shop will let you do this. Rank them all. That way, if you repeat this at another fly shop, hopefully one or two of the models will overlap, and you can use it as a placeholder. "Ok, so I liked the XXX better than the YYY at the first shop, and at the 2nd, I liked the YYY better than the ZZZ, so I must like the XXX better than the ZZZ too."
