Nice rod! The SLT is one of my favorite series that Sage produces.
As far a reel in that price range, there's several that would fit the bill. Bauer Mackenzie Super Lite M4SL. Nautilus Reels puts out a nice product. Ross Big Game 4. Islander Reel. There's so many... ;D
My 8wt has a 3.75" Hardy Bougle Mk 4 on it, and I just picked up a Gem MK II for the 9140 and to fish the salt...but Hardy is not everyone's cup of tea. I love them, though.
