If you like the rod, then you should diffidently rebuild it.
I do it often. The last one was a $25 IM6 8wt. It got stripped to the bone and then got a new seat, grip, and guides including 3 more guides than the original. It's a better rod now than when it was new.
Another one of my rods has been rebuilt so many times that the only original piece is the butt section of the 2 piece blank. That rod is on it's third grip.
