Thanks verendus. I casted saturday and sunday and though I got plenty of line out there, it felt a bit heavy and sluggish. I casted 525 on Sunday and I definitely liked it a bit better. felt quite a bit more crisp and was able to turn over a good 10ft of T-14 + a moderately weighed fly and shoot it out a good 80ft.Glad you ended up getting the rod. I am the guy with the T&T 1307.
FYI, you should try to stick with 550. I think Bob would recommended even higher grain weight, but, 550 should be fine. Unless you have a really aggressive top hand stroke, the rod will rod the line fine and shoot it out. I know some accomplished caster who shoot 600 on that rod.
I think 500 might be a bit on the light side if you plan to throw a decent size flies.
