Replying to JJ's vs. Bacons

i searched for a thread like this before, but no dice.
i've been racing up to this year, i have invaders as a park ski, and i'm going to be skiing mostly at whistler. I'm 5,10 and 150 pounds. I was originally set on the bacons, but i might be wanting early rise now, despite never trying it. I also am concerned if the 185 jj will not be long enough for me. Has anyone tried the new jj's? are they a controllable rocker? also- would it be worth it to but an at binding on the bacons?
if you could help me out here it'd be awesome/
