STR8 bowling4 my 01st marathon.used two 8lb URETHANE by Planet X Straight ball 27 games 10-12-25

My camera had plastic on the lens is why the videos I made with this one & the ones before it were not as clear as they should have been.
Bowled 27 games in 3 hours with a 200 high 26th game with a 150 avg for these 27 games bowled with the Planet X Urethane bowling balls.
best so far is the 200 for the 26th game & had a couple hambones or 4 strikes in a row.
I bowled with 2 used Planet X 8lb balls not fet to my hand yet. I drilled the thumb a little bit bigger so I could get my thumb in the ball for the str8 ball.
my thumb shrinks after about 7 games then I was able to get my thumb with tape in the ball. but I still could not get my thumb in the ball all the way but with my thumb sticking out of the thumb hole about a half inch so almost all the way in the ball as the conventional grip.
The Conventional grip for bowling is with your middle & ring fingers in the ball to the second joint on your fingers with your thumb all the way in the ball where as the finger tip drill is only the first joint on your fingers in the ball.
