A slack 953 frame like an LTHT but with 2″ of fairly stiff single pivot travel to go with a 140-150mm fork. Just a little give for flexing into corners and a smidge for landings; but by no means a compensator. Single pivot for a single piece back end and low maintenance & no weird bearing sizes! CNCd tapered headtube, or maybe a machined hourglass 44mm? Offset insert thingybobies at the pivot for more tweakery of the geometry to match fork choices/preferences.
Polished or brushed, straight-ish tubes, swap-outs for fettling potential. Simple, stainless and with options. The bastard son of a softtail, 4x bike and a LTHT.
