+1!Yeh, I'd look for a set of 1 1/4" diamter bars if it were me. They look a little "phatter" and it will make running the multiple wires a lot easier.
When I ran internal wiring on my old V2K....their were appx. 10 wires per side that had to be extended, soldered, shrinkwrapped and run through the inside of the bar. That extra 1/4" may make a whole lot of difference.
