I bought a 16lb track rule delta 1 x-blem on e-bay.
It has 2.25tw 4-5 pin.
I would like a drill for med-heavy oil. Can it be
done with this long pin.
I am a stroker type bowler with a high ball track
just outside finger & thumb. I turn the ball very
little,mostly stay behind the ball at release.
Ball speed 17-18.
