The league I bowl in the majority of the bowlers are using equipment between 10-15 years old. There's only a handful that are using newer gear. There's about 4 of us who use newer gear, 2 are using DV8 and me and another guy are using newer storm balls.
Alot of storm but it's older stuff, Erasers, Diablo, Thunder Roads, and several from the X-Factor line.
The 2 that are using the new stuff, I've been using the IQTP, Marvel Pearl and Victory Road just about every week. The other guy has been using the Vivid, Lucid, and Sync.
