I do not recommend hitting these balls...unless your team is sponsored by REI. Sure hitting HRs is fun, but tracking down these balls after being hit takes expedition level efforts. We held a HR derby for underprivelidged children (age 6-10) and they were hitting bombs that landed in other counties. Seriously, if you purchase these balls you may want to look into renting some sherpas and a yak so you don't have to shag them. At one point a ball was hit so far it showed up in North Korean airspace and Kunsan had to scramble fighters. I mean, these balls are ridiculous, Verne Troyer goes yard with them.
