Using production hard parts and following production specs won’t cause binding. That’s usually caused by messing with servo internals, front clutch release spring stack, and sometimes messing with the valve body.
Most guys tend to stick with the middle of the spec range for clurch clearance but you will be fine where you are.
As for the waffle discs, they provide more lube to the clutch discs which helps cool the clutch - like in snow plow use, frequent reverse applications. The other theory is that the waffle grid wipes the oil off the steels faster instead of hydroplaning.
