Why in the world would you want to ruin a good rack of ribs
They haven't done you any harm,why GOOF them up
You're gonna have them in the (Lord forgive him)oven for 3 hrs. then the smoker for 3hrs.;so why not just do it all in the smoker
You will be missing all that love in the oven;and being Summer,it is just more fun
Get a meat-thermometer from the grocery store(about$3),and use it in the smoker to keep your heat to 250*F(a small hole at grill height does perfect to push the therm. through
you won't have to turn them,just place bone side down. Put them in on the grate for 3hrs.,then wrap in foil(tightly with a touch of liquid-Beer,Tea,Cola---) for 2hrs. then open te foil anr let them go for one more hour.Any other way is a "SIN"
If you have to use a charcoal,at least get a good one,Kingsford Competition or such;hopefully you will go all wood-it too will light in the charcoal chimmney.
Good luck and,
