727 rebuild opinions/thoughts welcome

I never use any measuring devices. I install the drums without clutches and the pump minus the gasket and o-ring; without installing the front band. I pull in and out on the input shaft and guess at the clearance. Then I install thrust washers to get to about .020. I install a thick washer between the drums and I do not use steel shims between the shafts. Sometimes I use two thin washers at the front. Barely feeling any endplay in a cold case (without the pump gasket) is what I'm looking for. I switch snap rings and sometimes even fibers to get the clearance I want in the clutch packs. I see all kinds of huge clearances like .100" posted but I always make mine about half that; no matter how many frictions.
