I was offered through subscription, the 2004 Syrah Thompson for $36 direct from Ojai. I have never had the Whitehawk Syrah but the White Hawk Chardonnay is great.  Apples to oranges I know or better Syrah to Chardonnay comparison I know. 
 
Anyway the $31.99 price is a good price and I would go with Whitehawk, then Roll Ranch then Thompson, but they are all good. Look up Molly Dooker Shiraz, all of their Shiraz's are great and I am going to place an order before I leave for RAMF.
