Notes: Here, I've gone in a little bit tighter (around 30 delta for the shorts) to bring in a little more credit and am keeping the wings somewhat tight because, well, it's a piece of crap with monthlies only, so I don't want to hang a lot of BP out there if it causes me trouble because I'll have to roll from month to month.
