I'll be interested to hear what you do. Those that figured out how to do it correctly (or get coached well enough) I have found like it, and in a way its simpler. But not all for sure.
Just from reading about it, I have been practicing enough that I shift cluchless up and down every shift when Riding at hwy speeds. Riding my dirt bike, I started experimenting and found how easy it was and then moved it over to my street bike. It took some practice and I still don't get it right every time, but I sure do like the way the bike feels when I'm riding aggressively.
