Sdbowler,
I don't think there is anything wrong with the ST Turbo Xs. I've known quite a few guys who have bought them, and nobody has ever complained. They were/are made by Ebonite, so it's not like there should be that big of a difference. Some people just don't trust a ball once there is any kind of change. It's like when Ebonite changed their logo in the 90s. They made the Turbo X with a new logo and guys complained that it wasn't as good. Same ball, just different engraving. Same thing happended with the Panther, some people said they were better/worse than the Turbo X. They were the same ball, just a different color. People are always fickle.
A few years back, I knew a bunch of guys that used the ST Turbo Xs for our late shift scratch trio league. They hit fine, honor scores were thrown with them. None of them ever cracked or anything, so I can't see what the complaints could be. They are realatively low priced, hard hitting controllable balls. Just like the originals. Of course they are pretty week by today's standards, but they do quite well when the conditions are right. I almost drilled one up yesterday, but I got my hands on a 15lb Crush/R instead and figured I'd give that a try first.
