BBQ Sauce help. Opinions needed!!!!!

[MallenManson]

I need some serious help here (imagine that!) with Regional BBQ Sauces.

In the Spring, I'm going to do 4 Regional Sauce-Offs.
3 Sauces in each of the big 4 Regions:

Texas
KC
St Louis
Memphis

Not interested in Georgia vinegar based, Carolina Mustard based or Alabama White Sauce.

I will put 3 (maybe 4) sauces head to head to pick the winner of each Region.

I know we have guys from all over the country, and I know a lot of you love some BBQ!

What I need is, your Sauce recommendations, for any of the Regions you're familiar with. If you have a website to order a Sauce you recommend, that would be great!

Northern Michigan isn't exactly a BBQ hot spot, and quality sauces can be hard to find.

These are what I'm looking at so far:

Texas-
Dickey's
Salt Lick
Cousin's
Railhead
Sonny Bryan's
The first 4 are available at Dallas Airport, where I'll have a 2 1/2 hour layover

KC-
Cattlemen's KC Classic (Have it)
Texas Rib Rangers Original
Big Bob Gibson Red Sauce
Oklahoma Joe's Cowtown, or KC BBQ
Head Country Original
Lotta Bull Original
Slabs Kyle Style
Three Little Pigs-KC Competition

Memphis-
Cattlemen's Memphis Sweet (Have)
Sticky Fingers-Mild
Rendezvous

St Louis-
Pappy's Smokehouse-Original

I've been partial to Cattlemen's since my first bite of Authentic Smokehouse. Sadly, it's been discontinued. I may have the last 3 bottles on the planet. But I would put the KC and Memphis bottles aside, if I hear enough from you, to warrant that

One last question.....is anyone familiar with the Memphis Championship BBQ chain?
There's one here in Vegas (on vacation), and from what I can gather, their Sticky Red Sauce is St Louis style, and their Original is Memphis style.

The results will, of course, be posted here, along with gooey pics! May even youtube the process.

Any help would be greatly appreciated!!!!!
