Shawn - Welcome to the forum! I've not tried this myself but have seen posts before that imply that this is a way to get more ribs in a smoker (don't know if it works or not). Do a search on rolled ribs and I bet you'll come up with something.
On buying a an 08, 09 or 50, most will tell you to buy what you can afford. If you are going to do volume on a regular basis, definitely go with the 50. Me, I have the equivilent of an 08. It's just me and the Mrs. and a party or two during the year. We do just fine. Others will surely chime in and give you their opinion. Either way you go you will have a fine smoker. You'll not be disappointed!!!
Have fun!
