So I may be narrowing down my board options (finally).
basically I think i'll wind up with three boards, each approximating the three different designs I've liked so far (but "tuned" for noise level).
--One is a "topre substitute". This is going to be my smk with gray strongmans with sliders from an AEKII (with the rubber dampers).
--One is my TP2 substitute (until I get a real tp2 and harvest its white strongmans), which will be my AEKII white alps switches (now without dampers) installed into the dell at101w, with a piece of elec tape over the hammer to reduce the click a bit. Should be light and soft like the tp2 (approximately). (I might add dampers to this too).
--One is my endura pro (cushioned with rubber washer or o-rings to reduce clack, and greased springs to dampen the click). This basically should feel like a heavier version of the tp2 at that point.
So my three boards are basically: a quiet one, a light one, and a heavier one.
Based around the three basic switches I liked, and modded to taste in terms of noise level.
