I have the MBR GLX 783c and i think it's worth the extra money. Most sensitive rod I have. If your going to go with the IMX I think there are better brands for the price. All depends what you will be using the rod for. I want to get the glx 843 sometime, have heard from numerous people it's the best all around rod their is. The way i look at it is if I never would have bought it, I would be always wondering if I should have got the other one. Just my .02 Back monkey back ;D ;D ;D
