Well, as jdaddy says, it'll work. It's a little long to be ideal, but it'll work. If you were only going to do the brookie thing on occasion, I'd agree with him.
If you're going to be doing it alot, it makes sense to get a specialized tool for the job. Personally, I do like heavier weight lines, a 7'6" 5 wt would be perfect but can be hard to find. Many who think like me end up with 4 wts, and overline em a bit. Others like 2 and 3 wts.
I've only heard good things about the echo carbon, but never tried one. I use a Cortland GRX, 7'6" 4/5 wt, and love that, but I don't think they make it anymore. Pretty much everyone makes 3 and 4 wts in the 7-8' range, so it really depends on what you're looking for in action. I like hand cannons, and going that route, St. Croix Imperials are very nice rods, they make a 7' 3 wt and a 7'6" 4 wt and either would run you a touch over $200.
For brookie work, don't hesitate to really skimp on the reel. It's gotta balance the rod, and thats IT. Drag isn't really coming in to play, and you're gonna bang this thing around on rocks and such.
