Always ultra pro for me. Unless the card is miscut/slightly oversized then the same size Pro Mold it is :beer:
Something to note, the pro mold magnets are stronger - which may or may not be to your liking especially when your concerned about how snug you want the card within the holder.
Dude, you ask a LOT of questions. At the time of my writing this you have five threads on the first page of this forum and most of them can be answered with forum searches. In fact this one could have been asked in your other thread about One-Touches for Prime cards from earlier.
