Howdy BigTrout, and welcome back.
Ditto the above, so I’ll reiterate, and flesh things out a bit.
First, I'll answer your question -even though I haven't actually used a Redington rod. I've liked the Redington rods I've seen though. Many are on the fast side, which I happen to like. I felt I could do very well with those I've looked at in shops.
As to length, although I generally agree with "go as long as you can" – bc reach helps a lot – consider where you fish most, before you decide.
Some considerations are:
1). How much room you have to maneuver a rod. If you are fishing mid to larger creeks, streams, or rivers, which offer a fairly open canopy –then go longer. If you fish mostly smaller creeks with a more closed canopy, go shorter. If you do both, and you'll have only one rod, I'd suggest you not go 9 or 10ft, unless you are planning on adding to your arsenal soon. Owning a shorter (7 to 7-1/2) and a longer (9 to 10) will cover LOTS of trout water.
2). Presentation type: Length is an enormous advantage, but especially so when nymph, wet, and streamer fishing, and somewhat less so for dry fly.
3). Graphite Quality (weight/stiffness): For shorter rods, graphite quality matters less than for long rods bc, as you add length, you add weight and with lower quality graphite it simply takes more of it to get the rigidity needed. I save my pennies and not skimp on long rods, and am willing to “skimp” more on short rods. From what I’ve seen, rods more than 8ft require better graphite. I dunno where the CT fits in this spectrum; If you go long I’d definitely want to see one to know whether it feels “clubby” at longer lengths. If it’s a short rod, I’d mail order it without too much worry.
My rods run from 6 to 9-1/2, and over the course of the season, I end up using them all. My workhorse though, for the small to mid-sized creeks I fish most often, is an 8ft. This is also the length I choose for beginners at the game, so I can introduce them to everything from small to larger waters. An 8fter offers juuuuust enough reach to nymph with (and keep out of sight), yet can be handled reasonably well on a small stream if the canopy is not too tight. I find an 8-1/2 is a bit much on tighter spots and a 7-1/2 a bit short for nymphing where keeping line off the water is at its utmost importance.
Just to put it out there, in thinking ahead to the future… Those that fish a lot end up with multiple rods bc no one rod will do it all. It's like trying to play 18 holes of golf with one club. You can do it, but you won't get the most out of yourself or the water. The problem with a "one size fits all" approach is that, as you add rods to your arsenal, you may find the mid-length rod collects dust as there are simply better tools for, say, small stream closed canopy dry fly fishing, and mid to large stream nymphing. Again, owning a shorter (7 to 7-1/2) and a longer (9 to 10) will cover LOTS of trout water.
Hope this helps. It did me; I feel so much better.
