Pork butt and Chuck Roll

[Wade G]

Thinking of doing a pork butt and chuck roll together for the weekend. My concerns:
1) Which one should go on top, or does it matter?

2) Is there a significant difference in the time it will take, and if so, should I adjust the poundage to compensate?

3) Butcher says Chuck roll is $3.49/lb. does that sound high to anyone else, since pork is $1.99/lb (PS- still not yet a member of Sams or Costco).

Thanks.

I paid $1.79/lb. for chuck roll at Cash & Carry (select grade, I think).

I haven't done one together with a pork butt, but I'd put the pork butt on top and chuck roll on the bottom, just like the butt/brisket combo.

The 19-lber. I did took 21 hours. I've never had a pork butt take that long.
