Both Peel and Phillips have had their ups and downs. Peels decision to move to Sale completely ruined his international career, especially because he wasn't first choice at Sale when he first arrived. Pretty much every time he's played for Wales since his move, he's been pretty ordinary if not rubbish on occasion, although I can sumpathyse given that they'e usually been one off games. Still a player of his quality should have been able to step back in and perform. Phillips was poor post Lions tour up untill the WC. Still though, he was great in '08 and '09, and phenomenal on the Lions tour and during the WC. I can't comment on Peel's good form of late for Sale as I haven't the time to watch the Premiership.
I'd still have Phillips over Peel at the moment. Re-watched the 2004 game between Wales and SA earlier, and I've gotta admit that Peel was a joy to watch. He really fit in well with the way Ruddock wanted Wales to play. I'd love to see Peel back involved, but there really does seen to be something very wrong in his relationship with Gatland, Howley or whoever in the Wales coaching team. His inability to get released for training doesn't help either, but that's neither Peels, Sales or Gatlands fault.
