The old TP is being reassigned. Which OS to use?

[mdphoenix]

Now that I have my TP2, and Tom Tom 6 doesn't work for squat on it, I'm going to reactivate it on my TP strictly for GPS. So the question is - is 6.5 faster than 6.1? Is it any less of a hog? We're talking just bare OS here. I'm loading nothing else on the phone but Tom Tom. So I'm going to cook a ROM with only the essentials, and bump up the PagePool, then load TTN6.

So, 6.1 or 6.5?
