I'll chime in and side with Mark E on this one....I have trouble telling the differences between the different woods as well. For sure some are milder than others (and therefore, you can use more and not oversmoke -- pecan is a good example), and some are "heavier than others (mesquite for example.) All of these recipes come down to personal taste anyway, so if you can't find exactly what BRITU calls for, use what you have on hand, and adjust anything that you feel necessary the next time you do it.
I currently use whatever wood I have. Last month I was finishing up a bag of cherry and a bag of hickory. Those are gone, so I'll dip into some oak, almond and peach.
I figure if I had a palate that could distinguish the subtle differences in wood smoke tastes I'd be broke.....'cuz I'd be buying more expensive wine, too!! /infopop/emoticons/icon_wink.gif
