It's a calculated risk. I have Axiom ICS running on .904 and things are running well. Antenna management is much improved and battery life is great.
However, the last time there was a major update leak (.901) a lot of folks ended up stranded since the official version ended up rolling to .902. It was a pain to get back on track.
I'm running .904, but that's because I'm happy to wipe my Bionic and start over if this version ends up being a dead end. If you're okay with starting from scratch from time to time, then load it. If not, then don't load it.
