Lots of good info from the experienced cooks/restaurant owners above.
To tag onto a couple of their comments.Sam's Club works with KCBS and most of the cooking associations.
If you are are a traveling team,you can find them many places,call ahead,and often order what you need.If you get used to cooking their products-which can be different according to their different distribution centers,you tend to know much about their products and your work with them.
I'm guessing many cooks in AL look for IBP fresh pork.We do, in much of the South, and they are common at Sam's.Talk to your Sam's managers and if they get three trucks a week,often they let you pick thru the shipments.Sam's enhances chicken parts,but not beef and pork.
Restaurant Depot also works well with these assoc.,as well.
If you have taken the Judge's class for Memphis,KCBS,and FLBBQ Assoc. you will know what the judges are looking for.[Some of our Master Judges just chuckled,as did our experienced cook teams]
But,you need to start somewhere.
Local butchers may cut what/how they want and think you should want to eat.We have found that they charge extra to cut their way and then it increases your work having to rebuild it for the judges' tent.
As Max says about personal dining,some of us may appreciate well preprared Heritage pork,as it is different from what we get at a lesser dining establishment than his.
DIFFERENT can mean" standing off" from what many judges are used to and maybe put off by.
We have cooked all across the SE and were fortunate to have sponsers for Heritage pork,as well.
Good,or bad, our team eventually all became Masters and Table Capts.We felt in tasting our own products and observing other judges, that sometimes folks felt there could be not only a different taste,but "mouthfeel".
You are in heavy Memphis comp areas,so find many teams cook loinbacks and judges get used to judging them.But,cook what you cook well.The judges that travel every week are mostly cross trained in all the comp standards and habits.
Cal is probably the most recent forum member to follow these tracks and might be one of the best to advise on what is near your area.It sure has brought him success.
Enjoy and remember it is consistent.A First may feel warm and fuzzy,but in AL large/good quality comps,four top ten's takes home the money.
