However it is a fact that most Honeycomb/ICS development now is on the 1.2bl branch. That means that when you switch over, your options for different ROMs is enlarged greatly. This ROM is the only HC ROM, that I am aware of, that still offers the option of flashing onto a 1.1bl.
BTW, when you do switch, it is a good idea to be sure that you NVFlash with an image that will enlarge the system partition. Some ROMs (notably Flashback) require the System partition to be larger than the stock Tap-n-Tap provided.
