costco had prime full packers for 3.30/lb in arlington tx last weekend!!! with that being said i've done 5 packers (from costco) and frankly i like the point much better than the flat so ive just been doing choice points recently. with the packers i noticed that it took quite a while to cook and i had to keep opening the lid and stoked the coal to keep it in the 250 to 270 range. also, depending on where the hanging is of the meat its going to drip and depending how much moisture is dropping off it could turn "off" those coals as that happened one time to me. another thing is, depending on where you put the cherry chunks makes a difference too as it could turn "off" the coal as well......which happened to me
my last brisket cooks have just been the point and they have come out fantastic every time. i took them to about 208 210 and as mentioned, probe goes in like butter and tastes perfect. not saying you can't do a full packer but try experimenting with different methods and once you learn your cooker it will be all good and fun!
btw, i was using full basket kb blue, lighter fluid, waiting 20-22 min to drop meat, mesquite chunks, 1/4 open vent, both rebar placed, and a smoke bomb. also, looking forward to seeing pics from your cook!
