We split ours in half before cooking. I don't think it matters too much. It should cook the same, no matter what size it is. This reminds me of a post where a guy asked about taking a whole brisket and cubing it while it was still raw and turning the entire thing into burnt ends. It should work, no matter what size or shape you cut it into. Might make a marginal difference in competition cooking where marginal differences determine the winners & the losers, but for a home cook, I think it would go fine.
Just my opinion.
