21 games bowled become a better Straight/Hook ball bowler #196 with the Brooklyn Crusher 9-24-23

bowled 21 games in 2 hours with avg of 171. used two 12lb Gems & two mix by storm.
Bowled wearing my tennis shoes with ZERO slide at the foul line. I throw right hand & have my right foot at the foul line as my front foot.
NO tape on my thumb. I bowled bare hand with nothing on my hand. that's one arm/hand throw:
For a str8 ball I use my thumb, for hook I don't use my thumb. using your thumb creates more end over end roll. a no thumb throw creates more on its side roll.
To create the most on its side roll I throw with all finger life & around the ball for leverage.
If I want less hook I throw more end over end roll verses side roll. if I want more hook I throw the ball more on its side roll then end over end.
