This thread inspired me to borrow FlowFit from a friend, just to see what's new.
In the end, I like it. It's cut down a lot of the more challenging stuff from the original GTB (some of them were lots of fun though!), and seems to be less space intensive. There are some clearer progressions to follow.
There's overlap with Scott's other videos I'm sure, but it appears to be a good stand alone
I think it may suit your purposes, Cliff - though I still recommend you chat to the folks on Rmax to get their perspective.
