Yeah, I am 5'11" w/shoes and longish inseam and the large is just about perfect sizing for me, but run it with 45mm stem (could easily go 35mm), bars rolled in a bit and saddle pushed all the way forward to max position, so a shorter ETT would be nice at around 23.5". The 18" ST is just about ideal for me, could maybe go 17.5" at the smallest even when using platform shoes already. Ideally, the SO could drop about an inch, BB at least a 1/3" drop (my Rune's BB is currently 13.85" with 2.3 tires, slacker angled cups, 170 fork w/external HS and feels a bit on the high side even with 30% sag, especially since going up to bigger fork from 160 w/13.7" BB all of last year with approx. 27% sag).
BTW, for "dunerinaz", I did a bunch of riding while on trip this past spring to the SW (Sedona, PHX). I rode all the major techy stuff and never felt the BB was too low at 13.7" with my set-up at the time (it was actually lower to about 13.3" when I would frequently drop the fork "on the fly" to 115mm for all of the trail climbs or any techy inclines for that matter with no strikes, problems or pedal feedback whatsover with ISX-6 air shock, tubeless tires, 13.7" BB at 27% sag on 215lb rider fully geared. Unless running >30% on super linear shock and very low psi in tires at heavy rider weight in very chunderish terrain, would I feel a <13.5" BB possibly being too low. Bikes with BB near 14" or definitely above is just too high for all kinds of riding, IMO and why it is more common to see full on DH bikes these days with even much lower BB's than they used to be. Lower bikes ride faster and are more fun to ride, plain and simple, unless you are the type who frets hitting your pedals on things all the time or don't ride with pedals in the leveled, paralleled position when cruising at high speed through chunk.
