Well, I used my Eraser, for only the second time, since i got it on Jan 20th, and tonight was my scratch league, and i started out throwing 12-13 to 5 and having it hit the pocket with a ton of force, my first game was a 237. And i was warned that this ball burns up the track fast, so i watched out for it setting up early. my second game, i couldnt throw 12 to 5, i had to move over two boards and throw 15-5 with a little bit more speed. I ended up throwing a 171 game, my fault, i had three splits from tring to keep on using the 12 to 5 line, but it was setting up a bit early. But during the third game i ended up playing my normal line, with is like 18-10 sometimes 5 depending on my speed and the lanes, but with this ball it didnt matter, if it was 10 or 5 i hit pocket everytime, and as long as i put a bit more into it when i knew my release wasnt right i was kewl, i mean, i cant say enough about this ball, its great, and hits like a ton, too, i ended up shooting 221,for that game. I also used this ball on my monday night league which is in a different, house, and doesnt oil the lanes as much, and at first, i had problems because i was tring to crank on the ball to much. But when i was done i practiced and got some very helpful advise, from the guy who drilled the ball up for me, and i ended up changing my release, and put a whole lot less on the ball and basically just game the ball the revs from my swing, and i was playing 20 to 5 and hitting pocket with a unreal force, so, i would deffinetly say this is a ball to get.
