Nice discussion about the need to hang off or not. If you can achieve equal laptimes with both techniques, what does it matter which one you use. It will become your personal choice of what you like or not, not a SUM of calculations on angles and forces that should lead to the optimum style for the fastest lap time.
For me I really like to wrestle my GSXR1000 around with some decent physical input from my 6f4 body. Why, because it is fun. The same why my track mate on his Ducati 1098 is acting like a Hailwood replica, and having the same amount of fun. Unless you're doing competition, laptimes become more of a priority. For trackdays riders like me fun comes first, and with it a riding style you feel happy with.
