I'm running the same setup and if you ad a large bore master cylinder to the mix, the improvement is half again what the four pot calipers do. I used a 02 cbr 954 master and it was almost a direct bolt on, just a little dremmel work to square off the counter sink on the pivot bolt.
The six pots youre thinking of came on tlr's and some late 90's gixxers. They are OLD tech and the newer gixxer four pots are a MUCH better caliper.
