I join a league this year after about a ten year layoff. I started out with my old Blue Hammer 15lb. I carry a 168 ave. ,and as in the pass I left a lot of 7 pins , due to being left handed, but also the Hammer has always left the 7 pins for me . So I bought a new Track 505 in Nov.  after one mouth of getting use to the new ball  I am carrying a 170 ave . I know it does not sound like much, but my ave drop down to 165 before it started comming back up. With the new ball in Dec. I carried a 178 ave. and in the first two of Jan I am boiling 188 ave. I hope before this year is over I will get my first 600 series.  Last week I had 18 stricks and a 580 series. If I win I am going to pick the New Hammer Jigsaw. Be cause I can always count on the Hammer for 9 pins.
