With this poor display, surely I will not be able to discern the difference between the two versions, but I'm sure whichever will be the one chosen, it will be a good one! And, the fact that will be called just V2.2 will avoid some confusion!
Sounds good for a 2015 project! Go ahead like this, and, by the way, Happy New Year, and I wish you will start a lot of new projects!!!
