You go to where the work is at. Sheh hasn't had the luxury of Kate Higgins, Travis Willingham, and Steve Blum of breaking into pre-lay. That's why Carrie Savage relocated to Texas when LA stopped giving her work, because FUNimation gives her work galore. That's why Chris Patton's started working for FUNimation again.
This is not odd.
Also, there is a LOT of little-known/new talent in the Strike Witches dub. I might watch an episode or two just to hear the voices even though I have ZERO interest in the show and actually slightly appalled by it.
Also, on another note, Chuck Yeager is well-aware he's been turned into a moe-girl, his MySpace got spammed with comments on that when Strike Witches was released in Japan.
