Some students have difficulty or resistance when it comes to focusing on the purpose of drills.
Using the ETT premise as detailed by Onder Gurkan and Juha Maja of the ETBF team, would you advise the bowler roll a straight ball until they consistently successfully execute the drill?
Oct 20 2018 -Correction, I meant to say Onder's 5 to 5 drill which is done to train for ETT, sort of step 1 before more difficult trajectories.
I checked to see if the jpg was available on the forum it's in this link
viewtopic.php?f=20&t=13078Two obstacles to success that I see sometimes, is the students preoccupation with the release and a failure to hold (post) their shot at the foul line until the ball falls into the pit.
Holding foul line position gives feedback on balance.
Using a straight ball, the bowler could be instructed to roll the ball straight up the 8 board.
Ideally, that shot would hit the 6 pin dead center (reverse for LHB).
The focal point diagram shows the 6 pin occupying boards 7 through 11.
Richard Schockley uses a piece of white tape on his forearm, near the spot where blood is commonly drawn from. Rich Carruba uses the cue, "Give blood to the pins", both of these to help avoid arm turning.
Including Schockley's video

Put a piece of white tape on your PAP. When you can at least make it face the left gutter (straight ball) you are behind it at release. Don't try to hook it (or dont try to turn your hand). Once you have that under control, then you can start adding turn with the hand.
I teach that you cant hook it properly until you can roll it straight properly. Also helps on spares.
