Replying to Brigade/Prophet 100 for "second ski"?

Here it is people:

I'm about 6'1", 165 lbs, pretty aggressive, ski in the alps. I have 179 Fujatives for park-only days and need a new second ski for an everyday driver. So its gonna be for about 1/3 park, 1/3 groomers/hardpack, 1/3 big mountain/pow.

However, I'm in two minds: do I get 185 brigades for their versatility from the park to the big mtn, knowing that next year my fujitives can be replaced by a proper all mtn twin like chronics, ar6s etc

OR...

do I get the beefier 186 prophet 100s which would charge better, but noone seems to ride them in the park- Will I suffer a bit this year (7 weeks in total) trying to ski the prophets through the park, but next year I'll have a more well-rounded setup...

I guess what it comes down to is how well prophets would compare in the park to brigades, bearing in mind the directional flex & geometry, and how heavy are the two in comparison? no rails, no pipe on these and slow spins <720. 

who can solve this for me?

Thanks
