I didn't notice you asking about these characteristics in your OP, so I thought I'd chime in. Feel free to ignore me, because I am far from an accomplished nympher. I've pulled it off, but I'm still experimenting.
Please don't take my reply as blowing you off I just don't know of any other way to handle this situation. Unfortunately, I do not know anyone who owns one of these set-ups and know for a fact that unless I was to purchase a guided trip a fly shop will not let me take each rod and a reel to the river for an hour or so. I feel that I can get a good idea how the rod handles and the sensitivity of feel by doing as I described above.
All that said if someone knows of a better option please chime in as I am all ears.
