I like a properly tuned CRF in my repeaters just because I like the way they feed. A poorly tuned CRF is worse than any push feed action will ever be. A center feed magazine on a push feed action is really just as good though. I'm not a PRS shooter but I don know a handful of guys shooting either ARC Mausingfield or Nucleus actions and one guy who's using one of the Defiance CRF actions. Then there are all the folks using the TL3 which is considered a CRF, even though it doesn't have a non-rotating claw extractor like a Win 70/Ruger 77 mkII/Mauser action.
