Amphib plus grass plus shimmy usually don't belong in the one sentence.
Before YSHR was sealed, amphib Beavers and Caravans coped with mud, rocks and grass for years. Don't have the problems with brakes now that the strip has been sealed.
Amphibs do run higher tyre pressures so soft is not particularly good.
