Congrats!! Like the others say... A pork butt is a great first smoke... but for me, it's the only smoke I've messed up so far. I've done 8 Briskets in 2 months with no issues, but I listened to a faulty temperature probe on a pork butt, when I knew it wasn't done, and screwed that up. So... my .02.... do a pork butt, but until you're comfortable with all of your equipment, go by feel. You'll know it's right by the feel of the meat.
