The main reason for going to a Rev 2 is not to make a speedy indoor kite. Really, the main reason was initially to have an indoor kite that I can keep in my book bag in case of "emergencies". Ignoring the obvious speed increase, I think the Rev 2 will give better reverse flight, slides, and axels than the current rev indoor does. I would probably never use a rev 2 in any indoor performance, but you never know.
As for different paced indoor performances, I agree that there needs to be some degree of precision, but I think that the best competition routine is built off of variation. This includes the fast, the slow, the grace, the flips, and the tricks. Obviously, I tend to lean towards the fast flippy tricky option because that's just how I roll. (Just to make sure, I am in no way denying you your opinion or declaring you to be wrong, but just that I believe that slow and graceful alone does not make a good performance.)
