I learned the hard way that besides the extra 9 inches the 3113m and 3106 are completely different (not all bad) rods. I have a CT2106, CT3106, SA3106, SA4110, and the aforementioned GSH3113m. They are all excellent rods and they can all handle bigger fish both on the salt and in the river. Just forces you to handle the fight differently depending what you're fishing. If I had to choose 1 all rounder it would be the 3106. Wish I found the below information before so I didn't have to buy every single one. I found this below online (from Brian Babcock) too late as there is tonnes of debate and chit chat on colours and models. In hindsight I would have passed on the GSH3113m and the SA4110 (the 3106 has plenty of backbone for tyees)
Can I say this any clearer - THE NEW GREEN BLANKS ARE NOT A HIGHER MODULUS GRAPHITE!! They are identical to the most recent brown blanks in everything except colour and logo. Trust me. It was my baby. Here's how a few cross-over:
Brown GSH3113M = Green CP3113M = Green CT3113M
Brown GSH4110 = Green CT4110 = Blue SA4110
Brown GSH2106 = Green CT2106
Brown GSH3106L = Green CP3106L
Brown Glll 290 = Green CT290F ***Note this is Glll material both brown and green***
So any of the brown "GSH" models used Gl graphite and they now come out as green (or blue for the SA's) with the CT, CP, or SA designation followed by the model number. Any of the brown Glll models (286,290,296,386,390,396) used Glll (higher modulus) graphite and they now come out as green CT(model number)(letter F).
Where someone answering the phones at Sage may be mistaken is assuming that we went to all Glll with the colour change. We did not! Any of the "new" green blanks that don't have the letter "F" attached are still using Gl graphite. To further emphasize this point, I am currently waiting for Sage to run a large order of Gear blanks and it is being delayed because Sage doesn't have enough Gl in stock. These are the only rods they use that graphite on.
I really can't say any more on this. I'm sure there will be some that refuse to believe what I'm saying even though I was Sage's Product Manager for Gear when all this occurred. It's obviously a conspiracy on my part to fool everyone into thinking that Sage is still using the same technology as they did 20 years ago! Would that make any sense???
