My opinion of both Sizer and Wiley in the context of either of them being PR writters, is of little consequence no matter how bad they are. I hear once Sizers contract is done there will be a new PR firm hired, hopefully a good one! I have relayed my opinion to both Sizer and Wiley that a PR firm can make or break a firm.
As for nathan, he does good DD work and makes good decisions about when to buy and sell, at least the ones I know of. Thats really all I care to say!
