Wobbles in mid turn are likely a rear end problem... Your shock might be sprung too loose & allowing too much rebound & compression... time to get that sorted out.

And as has been said, a loose grip on the bar is required so that you are not transferring the negative forces back to the chassis. Its a bitch to do though when your instincts are telling you to do otherwise. This is why you often see in wrecks the bike keep on going fine after it has tossed the rider... it wants to keep going straight...
