Yep I used wide foil all the way across the lower grate. Essentially allowing the fire / smoke to come up front and back - wide foil leaves about a 1-2 inch gap all the way across front and back which is perfect. I had the two big drip pans that came with the kk42 as well as one smaller one wedged in one side that covered most of the lower grate. I can take a picture once my grates are clean of the arrangement - soaking them now. I would say this setup did not catch 100% of the grease but close. The KK is certainly no worse for wear. All of the bbq came out great, too. Just a crapload of work. Started the cook around 10am sat. Was finally done at 4am Sunday. I held done butts in a hot cooler. Had one with an ice water bath going to cool it down quickly as I pulled it and put each butt in vac sealed bags. I pulled 3 butts worth and bagged the 12 -15 bags, allowed the bags to cool in the cold cooler for 30 mins, then cleaned the utensils and repeated the process until done. Hot bbq stayed hot. Pulled Q cooled down fast. Now I have around 50 vac sealed bags ready to roll. Sent from my iPhone using Tapatalk
