I returned to bowling after 5 years, I plugged a ball and tried sarge easter.  I am liking the drilling. I will keep it.  I was use to pin placements and layouts base off of my high track.  Now hat its changed upon my return,  What are some good pin placements/layouts for low to mid tracks.  Also will I still need to buy balls with 3-4 inch pins or can they be small now? like 1-2inches or 2-3
