Brian:
True experts on CPC do frequent this forum, so hopefully they will chime in. And perhaps I am wrong, but it is my recollection that Raynor did do A [/b] routing for CPC, but that MacKenzie did is own without consultation of such. Of course this remains a great debate - as does the differences, if any, between the two - and one of the holy grails of golf is the actual Raynor routing, which apparently some have seen but can only speak about if they kill you or themselves shortly after.
So it remains VERY difficult to call CPC a Raynor, or give him any real credit for it.
But as I say, hopefully the real experts will chime in.
As for MPCC Dunes, well to me it's more Rees than Raynor, but the club lists it as a Raynor and that's good enough for me. The course description on here says all you need to know.
