I'm having friends over for Labor Day. Ralph's has tri tip on sale ($1.77/lb) but I have one guest who doesn't eat red meat. I'm new at this but have had success w/vertical chicken but have never tried tri tip. Can you cook t tip low & slow? or will this dry it out? It looks like folks cook their t.t. over a moderate temp, more like 350 or higher. Should I just fire up the Performer for the tri's and do the chicken on the WSM? Thanks Peg
