It is an interesting topic. I think the teammate question is really a no-brainer right? IF you are cooking with someone, you will both know what each other is doing... or you arent an effective team.
But as far as knowledge in general: I have learned from the HoDeDos, Strawberry Hill Smokers, Sparkle Plenty (the original Sparky, and Rick both), Pig Newton, The Slabs, 4 Men and a Pig, you name it.. other names like Pork Pullin Plowboys (have to include todd, even if we are teammates, right?), KC Can Crew, Mokan Meatheads, are all in there too. I've had alot of learning over the years in my comp. bbq.
Anyone that asks a question, will always get a straight answer from me. I have no problem draggin ya into the trailer to demo a technique, share a rub, etc. IT happens all the time. Heck, my wife even more so than I do -- I think she holds box class at almost every comp. LOL I do that because folks did it for me. I have gotten guidance from folks whenever I asked...and sometimes when I didnt. I like to think that some folks have scored better thanks to my input. That is what it is all about it! I know alot of folks helped me get to where I am today, competitively.
I think Matt asked "why a class, when you can google".... I think there is a deliniation to be drawn. The value of the class is this: You get the full package in one place, in context, and in a proven process. That process is key, as is the context. Googling a technique, does not put it in context with the other three things you are managing at a contest,nor does it plug it into the overall process for you. To build that takes time... lots of cooking to build the processes and overall cook successes. The Comp class is a new phenom... with more money out there, folks want to shorten the learning curve and get a shot at those $$ and the rush of the name call "now". without building the process themselves. So yes, while you can google the techniques, putting them together in a cohesive package is the value of the class.
I answer questions all the time, but they are specific to a certain topic, or rough spot someone might be having.... I dont provide the whole picture end to end in context. I would expect a fee for that. I have over 15 years putting it all together. that is where the extra value is extracted.
Having said that, most classes I have taught were not for competitors. I have 6 classes and a handful of demos under my belt, and none were for competitors. And the prices reflect that: $50-$250 head depending on the topic, lenght of time, etc. IF you pay $500 or $750 for a class, there is an expectation that you will do better with what you have learned. To me that is a whole new level of competition... besting yourself. I think it takes alot to have the guts to do the teaching of a "competition" class - the people in your class are putting thier trust in you, (and thier $$); I am sure the instructors genuinely want to see the class pay off with success on the student's part. I know I would feel like I broke that trust of my student, or "undersold" -- If that student didnt show any improvement. It takes alot to be able to teach that, and teach it effectively. My hats off to Rod, Johnny, Mike D., MM, that teach the specifically comp classes... it is alot of pressure to perform - and to do it, and see the successes thier students have, is a testament to the champions they are.
