Hi Deansy, 07 was an OK vintage, wait for 2010 though, it's awesome.
Do yourself a favor, ditch the Bin28 for Yalumba 2009 The Cigar, a top Coonawarra Cab Sauv at the same price.
As for RMG I hope it works out for everyone, it didn't work out for me. I suspect the only reason why so many are still in is because they cannot sell due to lack of interest from buyers / investors.
Cheers
