The initial setting was just the "Your recommendation" option on the site. I don't know the precise depth in millimeter. So X+5 or 6mm. Giving it 7 or 8 palm lathers made a difference, too. Contrary to popular belief synthetics do break in. Especially dense ones.
Loft length is so subjective that it's hard to to give a firm answer. Evo is pre-set, where the G5A you can have Andrew custom set to whatever loft you prefer for free, so I suppose G5A would be my recommendation to anybody particular about loft length. Neither brush is floppy at all.
They should not be compared to badgers. They're their own thing
They're very soft, more efficient (with both time and soap use), can take a lot of abuse, don't have to be broken in much, don't have to be soaked, dry faster, are inexpensive, cruelty free. I prefer them to naturals for these...
