Rib Rack Angle
I'm curious about the use of rib racks. I've had a couple, but am far from an expert. Is it "better" to have the ribs sit at a 45°-60° angle rather than perpendigular to the grate? If so, why? Which angle would you recommend? I asked about racks in the comp forum, and was told one thing to be careful of is the racks taking off rub. Does one or the other configuration help reduce that? How much space would you recommend between the racks? Does any of this matter between spare and back ribs? I guess what I'm getting at is, if I was going to build the "perfect" rib rack, how should it be designed from a geometric standpoint?
