Getting back into Bowling...

I used to really like bowling. I went to a fund raiser 3 weeks ago and won a ball in a raffle.
They guy I knew Mark Booke still owns the pro shop in Boca and I had him drill the ball. Part of the drilling process is he has you roll a couple of balls to see how it feels. He gave me one quick tip and I rolled 3 strikes in a row.
I recently went and took a lesson with Mark and here are 2 videos.
In the video with a too and bottom; the top is before and the bottom is the end of the lesson. This is the same time lapse.
