As far as I know, Simspon super badger is super badger and not sliver tip badger hair grade. I have a Chubby#2 super it is a fantastic brush but it definitively has not the soft feel of a silver tip, my Duke#2 feels slightly softer. By the way, what actually this Simpson super badger made of is not clear to me (it looks very much like a regraded best and the Simpson best is damn good).
A TGN short lofted brush would work fine, more expensive the D01 shavemac option should be considered especially the two band D01 (stick with 3 band if you're looking for an extra smooth feel).
I have a D01 two band 21mm knot 50mm loft, it drives easily through a soap puck and I cannot imagine a brush more appropriate to face lather (extra firm yet silk soft on the skin).
Shavemac 177 (23mm)
