The post on Kengarden (if you're just starting out, follow this blog, it's awesome kengarden.tumblr.com) said the new models don't feel sticky at all. It feels (quote) "velvety soft to the touch". I don't know if it's really cheating, since there is so much difference in paints. My translucent tribute is very slippery and does not wear in, those first lighthouses were a real challenge. And my yellow oozora had stable lighthouse right out of the package (mostly because of the rough base cup edge). And I don't consider an oozora cheating...
It's really like JamesFM said, you need to choose what you want to do with it. But I would start with a standard kendama, to get your basics down without to much help. So I guess the 2012 pro model is a great way to start, I heard nothing but good about them. And that paint is really not cheating ;-)
Have fun playing and welcome to the forum!
