i could say over priced brunswick, but that would be a lie! i have every ball elite makes but the eclipse, and i am very impressed and would never throw another company agian, even when other companys have offered me free stuff i turned it down!,  The easy of read when it comes to the lane condition is great i drilled all 10 with a similar drilling and i can biuld and hold a line for many games, and they  go to the next ball in line,  

But to get back on subject, I would eather use the Viper, or the green alien, the blue is for heavy oil and the green is for med to heavy, The shark is just to much some times, but i had a local center put down 40 ft of heavy oil, and then oil the heads, then i bowled and I was still throwing between 4th and 5th arrow.
