A lot of my teammates use them. A lot of overhand throwers use them. A lot of people in TX, OK, KS use them for their short range wind drivers.
In short though it comes down to supply and demand. In this case more of a demand issue, or lack there of.
We have 10 Elite-X Xtremes at the store, all blue and 173-174g. Feel free to drop me a line if interested, firstname.lastname@example.org.
