Watch twist the wrist 2 on YouTube, the one minus the cheese is best. My understanding is on track trail braking is used only as a supplement to you initial main braking, supposedly from the video it's best to brake then snap in over fast but at the last moment. Rolling on gently as soon as your at lean actually loads the bike correctly making you less likely to lose the front, sports bikes are apparently set up to have perfect 50-50 weight distribution with a progressive positive throttle, i.e holding a neutral throttle is actually loading the front because in a steep lean angle the bike will be slowing. It's much safer to have the rear slide a little than getting used to flying into a corner on neutral throttle. Obviously you don't do your serious rolling on until you coming right back up vertical. Just a gentle roll on thru all corners on the road even has made my riding 10x better, the bike feels so planted, add getting your upper body over to the inside mirror and your well on your way. So in an ideal world brake upright, slow in fast out.
