I've had a play around with this tonight worked with it over 22 yards and with the increased effort across the 22 yards comes the malfunction of the wrist position and the reduction in turn off the wicket. Speaking to Jim2109 he was saying that if you release the ball once it's past the vertical position the ball is going to be released with the seam angled so that the ball makes contact with the wicket on the smooth part of the ball and the answer maybe a loopier flight released slightly before the vertical position.
The session was better than expected and I'm able to bowl accurately whilst giving the ball a big flick ripping it with losts of spin, the problem seems to be in timing the release and or the wrist position on release, but overall it was another positive bowling session.
