Is it a forgone conclusion that the FFG Standard Card Game sleeves are the best fit? They seem pricey, $3 for 50. I can (and have) purchased "penny sleeves" from my local game store - 100 for $1 - but the fit isn't great (they're too long, resulting in an annoying plastic flap on top once the card is fully inserted, is that normal?), and I'm sure the materials aren't the best. There's also Mayday Card Game sleeves, $2 for 100. They seem higher quality but I'm not sure if the fit is ideal. Is there an obvious better choice; a brand I haven't considered?
I've never bothered with sleeves, but it's something I'm definitely interested in nowadays. I take pride in purchases moreso than I once did, during my misspent youth, back when money wasn't mine.
