I cant find my comments on the double tempo thing, but one important thing is that grounding the rhythms in half time bass allowed the beats to slide into top gear tempo wise - which meant people could still dance to it despite the accelerated tempo. If you check out a happy hardcore or deathchant type tune at 160+, there's no space, no groove, fast 4x4 obliterates nuance with its relentlessness, yet with jungle you can have these variations in pressure and gorgeously spacious rhythmscapes at the same tempo.
Incidentally, thats what got lost once the BPMs hit 180. there's a sweet spot there, roughly between 156 & 170.
