Well, the new ultimarc stick should come close...
yes, the ultrastick 360 does allow for some adjustment in most of these dimensions! for most of them, it's "choose A or B," not infinite adjustability, but even that already puts it far ahead of the competition in customizability.
i think if they went from "choose A or B" to "choose A, B, C, D, or E" for everything, their product would be asymptotically approaching perfection! it would also be cheaper and more reliable than something that was truly infinitely adjustable.
for the moment, i'm in love with my heavily customized happ p360's (kowal mod, lighter springs from supers, and wico universal red balltops adjusted to the perfect height - see the website in my sig for details). when i get the urge to tinker, i may try the ultrastick and see how it compares.
