I have the ESN on a T&T 3wrt 10' 9" Contact II. As already mentioned, it balances well with the heaviest weight. I like the reel but don't know if the ability to adjust weight is that big a deal. I used to have the reel on an 11' older Sage ESN rod and the set up was tip heavy. Didn't really bother me, but sometimes I would choke up on the handle and put my index finger on the blank. Would the heaviest weight be an issue for a 10' 2wt rod? Don't know but I doubt it. If I had to do it over again, I'd look harder at other options as well b/c "tuning" the weight doesn't seem like a big advantage to me at least. Just go with the heaviest reel that balances your longest rod and it should be fine for the shorter ones too. My POV.
