I have heard the different weights of the rod don't compare well necessarily across the board with competitors. For example, the Yellowstone Angler review (yes, take it with a grain of salt) ranks the 6 wt Sage One much better than they do the 5wt vs the peer competition. Don't know.
I just spent an hour and a half at the fountain and waterfall spring in my neighborhood, about a 100 foot circular pond with a waterfall and multiple smaller concrete enclosed pools. I can't imagine a better place to learn to cast a fly rod. My eyes are burning from the forest fires ravaging the mountains about 10 miles away here in Colorado Springs but the session allowed me to take my mind off the doom and gloom of the fire.
I tried to do an honest comparison of the Sage One vs my $179 Albright A-5 using the same reel (Ross Evo LT 2 lined with Rio Grand). Walking around the pool with the light breeze at different angles was a great way to compare.
-- The Sage One will blast it out there and if you "punch it" just right into the wind it casts like a bullet. Tossing a 2-fly nymph rig with spilt spot and and an indicator will not be a problem, especially into the wind. The wind ALWAYS blows here, 99% of the time and Murphy's Law says the Big Fat Brown will be directly into the wind under an undercut bank just at the edge of casting range. Mending should be easy with the One also.
-- The rod does not seem to roll cast as well as the cheapo Albright on those 25-35 ft roll casts.
-- Albright has an old shoe feel to it, need to cast slower but the rod does shockingly well given the price. And, this is coming from a guy without a lot of experience.
-- One is a bit more accurate, even in close...but not $525 more accurate.
-- There is a tendency to want to muscle the Sage and you have to force yourself not to. I think this is just habit from not being used to casting such a light rod. It feels so light your mind says to strong arm it when not required.
-- Albright is great out to 40 ft or so and then starts to get a but mushy.
Bottom line: Practicing at this pond is making me a better caster
