Well this was the first night to throw my doom at league and wow was i impressed. I went pin above ring finger to give it more of a snap look. Shot my first 600 series (i have only been bowling in a league for 3 months!). Shot a 190-235-242 with a 7-10 split in that last game. The ball was great, just throw it right and it will come back hard. also, noticed if i didn't get it to the right enough, it would hold the line and smash the strike pocket. Also, on weak pocket hits, pins would wiggle all over and i ended up with a strike almost every time. In all i am thankful i went with the Doom and not the BW pearl.
