got a cheapo smoker it stays at about 200degrees. the brisket it self is massive i probably will have to cut it into two halfs...one on the lower rack and one on the top rack. (i didn't buy it just doing a somebody a favor)... will cutting it into two effect the smoking making one tougher than the other. and how long to smoke at the above temp. i was thinking like 15hrs...any info would be nice (can't change the smoker or the brisket, got to do it no matter what, so please no "get another smoker" aint happening.
