I do not have the GLX (may change in a few days) but I do have the 2016 7'MH Legend Elite. Out of all the rods that I have used in the years I have been fishing the new Legend Elite is by far the best rod I have ever used. I've owned the rod for about a year and a half and I use it every time I go out on the water. I primarily use it for Trigs and jigs in the 1/4-3/8oz range but it will handle 1/2 oz jigs but that is as heavy of a jig I would use it with. That being said it is very versatile and can do the following techniques paddle tail swim baits, chatter baits, spinnerbaits, lipless cranks, powershot, and lighter Carolina rigs.
The sensitivity of the rod is outstanding it is by far the most sensitive rod I have ever used. The first time I used it I was using a 3/8 oz football jig and was dragging it along a rocky point. I couldn't believe how distinctly I could feel the bottom and I could feel every little change in the bottom.
As far as the power of the rod goes, it definitely feels like a true medium heavy. St. Croix rods are known to fish a power heavier than advertised but I feel that the 7'MH feels like a true MH. That being said it has a lot of power to pull fish out cover. Since I've owned the rod I've caught two 5lbers and one 6 all pitching a jig into lay downs.
The rod also balances well with just about any reel. I've paired it with Curado 200 and 70, Metaniums, and a Chronarch CI4 and it balanced perfectly with all of them.
I don't think you can go wrong with the Legend Elite
