SmokerBoy - It all as to do with your personal taste. What tickles your tastebuds may send mine into utter confusion! Personally, I dont do mesquite. Too bitter for me yet some Texans swear by it as the only way to do brisket. Do a search on woods. In general (and in my opinion) hickory is the king of smoking woods and gives a pretty heavy smoke. Oak and pecan are good all around woods.
Here's a link to smoking woods and their characteristics Do a search on the forum and get other smokers opinions. Just remember that your taste is what counts.
Welcome to the forum! Hope you have many fantastics smokes ahead of you.
