Wordpad thing, so I believe Mac can open those? [Isn't a Mac user]
Credits? Nah, no need. It's fine, really.
I saw a few tri flawless, I don't remember if there was any quad (4). But that was searching for 31/31/31. So you may have some good spreads but having 31's placed else where, so keep that in mind when searching that the spreads that have 31/31/31 might not always have the best spreads, as some might have 31's placed else where. You'll just have to do your best and look >.<
