Thanks for the reply PF.
Unfortunately, I don't recall the exact posts. I just read a couple things back in the 3K doldrums and made a mental note to look into it.
I am pretty frigging paranoid about messing with the old paper wallets...want to make sure I understand any modern pitfalls.
I am thinking that as long as I stick to P2PKH outputs, or sweep entire addresses I will be OK.
