Good luck to ya Lenny,
If you said what the flat weighed I missed it. Sorry.
The ones that I did this past weekend ran for about 12 hours in the sauna and another 4 in the hot box. My temps ran from 200 to 240 on occasion at a time or two.
I wrapped mine when I hit......... well I was drinking a little so I don't exactly remember what temp I wrapped at. I know thats bad but thats what happened.
Close to 200 they went in the hotbox and took a break.
They had a great smoke ring and excellent flavor thru and thru. May not have won a first place since they were just a little on the fall apart side. But thats the best way isnt it.
I hate to say it but I bet your flat is gonna run a little past dinner time. I hope I'm way off but 3:30 till now just doesnt seem like that long.
Any chance your taking pictures?
