Well, firstly every single high stakes MTT winner is god awful at SnG's. If you can value the crap out of azntracker this easily...then lol!

And in actual fact, this guy's more SnG than MTT as far as I'm aware. Well, there's a few exceptions from people transitioning the other way, SnG to MTT, but definitely not vice versa. Give Moorman a year in 18 or 45 mans and I'd be shocked if he's over break even.
Secondly, yes it's usually best to just plain shove a higher amount off BB's in MTT's because the money is way further off, average stacks are wayyyyyy bigger, and you're getting called wayyyyy lighter. Very simple theory.
In extreme circumstances, r/fing 8bbs and 3b/folding 12bbs is perfectly fine in SnG's. Very rare, but set ups for it do happen.
