Well, as I said, I think you overview is nice - it might help players unfamiliar to that decks a lot - and of course I know that there are a lot of Rol/Hope-decks out there, some fit those players better, other players like other builds. I just wanted to add some stats to your collection to show that you might get a better win rate with that concept than 40 % - if it's mostly due to luck, deck build or something else I do not know and I'm not here to advertise my build...
But talking about fastness: I think those Rol/Hope 30 card deck builds are all almost similarily fast, though more regeneration might mean you loose games a bit slower (but might get the chance to win some more), so that's no real argument in my oppinion.
