Reader, you need to know where you release the ball in relation to your slide foot. I have about a 7 board difference between my slide foot and my release. If I slide on 35/36, I can go over 19/20 with my spare ball to get the 6/10 pin. Everyone has their own methods. It's trial and error. You have to practice and come up with your own plan. I use the center arrow for all of my spares. Some people use the 3-6-9 board system for spares. I don't like that because if you bowl on PBA type of conditions or heavy oil, it isn't as reliable. Just my opinion. It has been said by many bowling gurus, " straighter is greater". Plastic balls take the lane condition out of the equation.
You have to find your foot positions by trial and error. It shouldn't be too hard. One practice session should do it. Keep a pen and paper handy and take notes.
Thank you. I cannot find my copy of Bowling Execution
I have been using the 3-6-9 spare system with my regular ball. It has made me use a different hand position and release for the ten pin, so it has taught me something about becoming more versatile.
However, with the pros and others recommending a straight plastic ball, I believe it is time to learn to use my Maxim.
I will start to pratice and record my foot position at the line.
