I've got 775s and 810s and came from 765s. Since you didn't find the 800s lacking, get the 775s. They have more power, better ergonomics, and excellent modulation. The 810s have a whole lot more power and better fade resistance. At 220 lbs, I find the modulation fine but some lighter riders find them a bit grabby. My favorite combo is 775s with an 810 front caliper.
