i want to say a big thank you to Track for producing the Arsenal Artillery! ever since i got this ball 3 months ago i have posted 2 high series (650) and today a (682) in my tuesday night scratch league. i have been a 175 average bowler for the past year but all my averages for my 3 leagues have risen by 5-7 pins each. this ball also got my high game of 278 and recently helped me to 3rd place in the english junior national championship. Thanks Track!
