Anytime you change the effective length of the handle you greatly increase the leverage of the rod. This actually helps in many ways including tip speed and being able to load the rod much better. Sounds like a nice improvement to the rod.
I have an 11' that I have the opposite problem, too much butt. I was thinking of cutting of 6" from the bottom but I'm afraid I'll screw up the balance and dynamics of it. Maybe I should sell it and start over again.
