So, you’re thinking of swapping out the E93 for the 99Ti AND getting the 108Ti/Enforcer or just using the 99Ti as the “wide ski” of the 2 ski quiver? If you’re planning on 3 skis, I’d keep the Monster 83s, E93 and then add either an E104 or MB108Ti as the “dedicated powder” ski. The E93 is a great ski on groomers and a bit of snow so you’d probably be sacrificing a bit of that harder snow performance for a bit for float in the 99Ti.
With Monsters, E93 and a “powder ski” you’d have a great hard snow, daily driver, fun powder ski quiver.
They had no MB108Ti to try but hear it should rip! Similar weight to the Enforcers/other MB models with a long 22.9m turning radius so it should be very stable at speed.
