same here! I think the only way is to just try stuff and take your time. I have never been on a track (yet!!) but i think that you still need to blip on the road. I even did it on my old R6 before i was t-boned and it was killed
I just use my first 2 fingers on the brakes and pinch the throttle tube with my thumb and third finger (i guess my little finger too as i have GP-Pro gloves and they are joined) The weight i do put through my hands is kind of taken in the bit of skin between my thumb and index finger. I dont really have that much weight through my hands as i read that you should still be able to flap your elbows about when you are doing it all properley.
Gripping the tank is hard for me though as when the r6 was written off my right femur was smashed and its not really that strong yet
