Hey Big Ir, good to see someone from Merritt Island! My roommate at UCF was from there. Ah, memories . . .
I've said it elsewhere, I think chicken is your best bet for the first cook, especially if you haven't done any kind of smoking before. I think beginners should stick to shorter cooks, like chicken or ribs. I've heard others say this, too. After 2 or 3 cooks you'll have an idea of how long it takes to get everything set up, and how everything works. Then you can start trying bigger cuts of meat, because you'll be able to budget your time better.
As far as the "50 degrees hotter" thing, don't worry about it too much. If you read through this board, you'll find that everyone has different experiences. Some people have problems keeping temps up, some have problems keeping temps down. Personally, I was lucky on my first cook. It went straight to 226 and stayed there. My cooker worked like magic. I barely had to touch it.
If you do decide to cook chicken, it actually would be okay if it ran hot, because many people like to cook it at higher temps anyway. However, don't let it run too low, as you might have a problem with bacteria.
Well, this is just my opinion, and I'm just a novice myself, so please don't think I'm pretending to be some kind of expert. If you don't like chicken, remember: it's your WSM. You are the master. Do whatever you want. Even if something doesn't come out as good as you wanted it, chances are you'll still be able to eat it, and you'll still receive compliments on it.
One last piece of advice: just try to relax and have fun. The cooker does most of the work. I was so wound up when I tried my first cook, which was pork butt that cooked for about 12 hours. 12 hours of worrying! Once the cooker settles on a temperature, it will stay there for a long time. So, go ahead and check it every 15 minutes if you like, but also don't be afraid to watch a ball game, or do some yard work, or chat with the neighbors. If you forget to check it one time, chances are you'll still be within a few degrees of where it was before. If you notice the temperature has moved away from where you want, don't worry! Just make an adjustment and you'll be fine.
