It depends on your comfort level. I tell most people they should have the safety net of being able to FXZ back to 905. But here's the thing....I've been working on the HoB since June. The thing has been battle tested by over 1200 users (yea, seriously). I've moved us forward through _11_ leaks so far. 247 is "probably" going to be OTA at this point. (I know, I said that about 246 but moto surprised everyone with this 247 leak). The process to move forward is proven by not just Bionic users but also the RAZR and D4 users. If you need the safety net of being able to FXZ to 905, stay on 232. If you can accept a bit of risk, 247 is a great build. I recommend a factory reset coming from such early builds as 232. It'll give you a better experience. So, up to you, but, I'm about to put out a new HoB version that speeds up the process in a few minutes.
