mine would have to be my columbia ego follwed closely by the orange messenger and cuda/c
the ego i found out was one of the most amazing balls i have laid my eyes on, i could do just about anything with that ball and it would want me to do more... since i have parted with it i have only found one ball that has been able to almost match it and thats the power drive also from columbia... those two balls got me my first 2 wins in adult tournaments... the orange messenger was the ball i threw my still highest game of 296 with and the cuda/c still rates as a powerful ball in my eyes....
