I'm no pro,but I have your cooker and do cook with some pros.
Like you said,you'll have to experiment.
If they sent you a box of wood samples,those large golf ball sized pieces often run about 2 oz each.
The cooker is very efficient in wood use,and it is easy to oversmoke.
Naturally ,it will take less hickory,than it might apple, citrus,alder,etc.
It doesn't flow a lot of air,so your smoke will stay with you awhile.
Cookshack is always conservative in estimates.
You ruin less that way.
You may find that 6 oz is more than you like, on some poultry,or fish,runs.
I'd try a butt and a brisket with 6 ozs and see.
You may wish to add another couple chunks,halfway through the cook.
I think you'll find that you won't get great smoke penetration into any large chunks of meat.
There are ways to increase your smoke levels,if need be.
As to the recipes,read them as ingredient guidelines,but let this forum be your guide as to times,temps,techniques.
Hope this helps a little.
