sound very similar to the shot laid out for me also lefty.
I have found that I have gone to slightly turning my wrist inorder to get a bit more on the ball to create a bit more in the back. I also have stepped back on the approach in order to set the ball a foot sooner on the lane.
The shot I am normally on is 41ft cristmas tree type out to the 6 board but at the end the heavy is still out to the 12 so if you get it ouside you don't get the recovery
