BogsOh, well the 100eight and 90eight are both designed specifically to be softer, more playful skis compared to the Mantra and Kendo, which as you probably know are both pretty substantial.
Are you looking for this to be a ski that you'll only be using on softer snow days?
Have you skiied the 100eight? It skis almost identically to a mantra just wider, definitely doesn't have much of a speed limit. It is replacing the gotama, which also worked quite well as a charger. I have spent alot of time on all of those skis including the kendo as they are in our demo fleet at the shop i work at. The reason it is still "playful" is because of a really mellow full rocker.
It may not be marketed as a charger but it is definitely not soft and it likes big drawn out turns. IMO it blasts through crud better than mantras despite not having metal. But that is probably due to the width. Mantra is a bit better on hardpack.
I would definitely leave that ski on the list especially for east coast.
As for OP, i would also look at 4rnt Devastator, or if you can get your hands on a gotama(discontinued) they are both really fun versatile skis, while still maintaining the ability to charge on hardpack or pow.
