I personally would take the GLX, it is IMO a better blank that is more sensitive.
I had the Dobyns 742 and its a nice rod, I ended up selling it and getting a Kistler Magnesium 3 with the NFC blank that I like a lot more.
I have the NRX in 852 in spinning and casting and its an amazing taper, I also have the GLX in 842 casting and its one of my favorite rods.
