Hi Jeff!
Sounds like you are having a great time with the new toy!! LOL
The only time I use rib racks is if I need them to cook lots of ribs. Otherwise, I lay flat. It is much easier to mop..if you mop...and just a lot easier to "baby" them.
If you use rib racks, half way thru you should flip them around so the bottom side is on the top side....does that make sense?
Anyway, enjoy!!
Stogie
