1st success changing speeds since switching to the left hand

My league last night was a struggle from the beginning.  I started out using my Hammer Toxic and it was rather inconsistent.  One time it would hook, and the next time it wouldn't.  Half was through the 1st game I decided to move left (I am left handed) and switch to my plastic ball.  It took me a couple of frames to get lined up, and I ended up rolling a 140.  After switching to my plastic ball at the end of the 1st game, I ended up rolling a 194 the 2nd game.  I had one open which was a 5-7 split and rolled 6 strikes (only had one double though).  At the end of the 2nd game, my ball was coming in high, and I was having to move right every couple of frames.  For the 3rd game, I moved left a couple of boards, moved back on the approach and lowered the starting position of my ball to increase the speed of my ball.  Even though I was rolling the ball faster, I had to concentrate on not rushing my feet.  I ended up rolling a 234 for the last game with 7 strikes (a double and a 5 bagger).
