Hi eric30,
Here is my best advice. Call Todd at
(937) 434-8472. He sells both Sage and Redington fly rods. Todd also fishes the rods he sells so he can give you a very good perspective on the Flight, RS4 and even the Redington CPX. Redington offers some really good rods for the money. So call or Email Todd at ReelFlyRod and take advantage of free shipping. If you buy a fly line and reel with the rod, Todd will spool everything and provide free backing. The best part of dealing with Todd is he is a great guy to deal with.
You should also check out the Sage VT2 that is listed in the Classifieds. It is offered at a good price for the outfit.
