I've been running it for a few days now, and I must say, it has changed the way I feel about sense roms. It's really smooth, no wifi drops, no 4g drops, and the battery life is actually really good. i popped in my stock battery and i can last easily 10 hours, with moderate usage.

 

Mik Runny and The bamf doubleshot are two other 3.5 ROMs, based on the Runnymede instead of the Bliss ROM. Have not tried any of them...just pointing out the options.

 

soab was the first rom i tried, don't know about the htc sync thing, but I liked it alot before moving on to liquid. Its a battery hog though.
