Greg, do not mix sleeves together, we have mentioned this in previous threads, for obvious reasons, ie some sleeves/ plastics can react with each other over time.
I have only ever used ultra pro sleeves, I have even gone as far as taking all sleeves out the folders that come with them and given them away to an old bloke I know that collects cards just so he does not have to buy any.
If you have used the sleeves that select and esp supply you will see how cheap and nasty they are.
Joel, it is not a stupid question, the only stupid question is the 1 you do not ask.
You don't learn if not asked.
This question is personal 1/preference.
as there are none made specifically I would go for a 4 pocket, just so there is some room around the card.
