Chris, I took his class in Dec of '12. If you have any questions let me know. Go hungry.
BTW, if anyone wants to talk about taking Myron's class, let's talk. :D
Is it a really thick flat? That's a long time for 5lb. Are you sure you're at 250f?
Last night I did a 14lb packer. It went on at midnight at 257f. At 6am it was wrapped and the temp increased to 275. It was done at 9am.
