More excellent suggestions. Drop bolts are a great suggestion but if you saw how long any little extra step takes me you would understand why I want to just slap on a new brake instead. (yes, I know how simple they are and I am shamed and embarrassed by this)

The 610s are too short, surprisingly. I dropped the intended front wheel into the fork and checked it out. I'll be burning through the sidewalls of the tires even at maximum reach. In back the 750 will reach the rim of the new wheel with no problem.
