Well,we all know Al cooks to be some of the fine ones in comps.
Al has many fine representative restaurants,and a pretty sophisticated bbq eating population.
I didn't say we were "the Master",as master judges are a designation of different levels of experience from judging over several years.
We have judged a lot of fine Al cooks,and they tend to like sweet,and sugar usage is prevalent.
Except for the use of mesquite,it sounds like you cook much like other FEC cooks.
Cris Lily,of Big Bob Gibsons,in Decatur,Al is one of the premier bbq cooks of all time.
Their Red Sauce is the" go to" sauce for many teams.
Here is an example of Chris' porkbutt/shoulder.
Chris Lily Pork ButtNot the answer,but one sample.
Often,expense,can be a problem for a commercial establishment,and sometimes rubs can be purchased in bulk,cheaper than making our own.
In comps,an entry box may be 50% bark-so it is important.
Many people will pack all the rub on a butt that it will hold.
There has to be some balance,so a lot of sugar may be used.
At comps,it would not be unusual to use 2 lb of rub and a pound of sugar,on a couple butts,and a couple briskets.
I'm not saying right or wrong,just stating.
Smokin' usually suggests folks try something several different ways,and take good notes.
There are several commercial rubs available,that seem to work well with pork.
Thus,maybe,four different rubs,on four butts,cooked all the way you like to cook.
Or,the same rub,and increase the sugars on each.
It seems you like your flavor,so to change the color and texture is usually a sugar thing.
Without us seeing your product,or you ours,and having a way to identify precisely how you would want something to change,you almost must experiment yourself.
Seems like several experienced cooks ,here,feel that the FEC s produce fine bark,and we all cook about the same.
Thus,it sounds like the rubs may be where we differ ,or the amount we use.
Also,you might be getting better bark than we do,and wish for something different.
Unless your rub has a REALLY strange ingredient,we probably don't need your ingredients.
Maybe, the weight/volume of rub on an 8 lb butt,and the amount of sugars[white/brown/turbinado,etc] you use with that amount of rub,will give someone an idea of which direction to begin.
We might also,be taking you the wrong direction,as this is subjective.
Someone might ask how to get more smoke and they already have more than we wish,as an example.
Once again,we'll try to help -if we can.
I'll get of here,before I get accused of makin' a Smokin'Okie post.
Hope this helps a little.
