Hi Nate: Just to avoid confusion ,each manufacturer seems to have a different system of designating the character of their rods. Sage uses a graphite modulus designation of GSH 3 for high. GSH 2 for lower modulus. High modulus means a snappier action. Then they give the length 113 meaning 11'3" or 106 meaning 10'6" This is followed by a designation mbr meaning medium weight bait action or lbr light bait rod.
I think they also have a heavy bait rod as well.
Loomis used to give tip diameter in 1/64" and a butt diameter plus a material designator GL1, 2, or 3 or IMX, or IM6
It would be nice if they got together and developed a system like the AFTMA system for flyline weights that all manufacturers could use
