In 2013, I was gifted a Gloomis 9' for 4wt StreamDance by a fellow BB member ( thanks, again, Karli ).
It is by far the best fly rod I've fished, out of somewhere around 10-12 over the years, to include rods by Powell, Sage, Winston, TFO and Hexagraph. Ninety percent of my fishing is dry only, no droppers. I do use a TFO BVK 9' for 5wt from nymphing and streamers.
The StreamDance is no longer available, but the rod you are talking about is, probably, in most regards something of an advancement from that model.
The StreamDance is a fast action rod with a rather soft tip that is very light in hand, is accurate closer in and can really rip the line for some distance. As far as "backbone" goes, I've landed a 36" B-run Clearwater River steelhead with this rod. Nuf said.
The only issue with my rod has been a somewhat fragile tip section. I've broken the tip section twice. Fortunately Gloomis has had a no-fault warranty replacement policy which gets you a brand new rod for $100 including shipping. That policy may or may not still be available - worth checking it out on their website for the model you are considering.
Hope this helps.

The fish are always right.
