Replying to Need an honest opinion whether this is overlap or totally unecessary quiver

ive been looking at two skis this season. 

first being the line prophet 90 and the other beings yours truly, the watch lifes. 

im more of an all mountain type of guy, but also looking to devote time to the park this season. 

i got my first pair of used twin tips last season, those being the black and white 2001 head mad trix. 

i was thinking of selling those mad trix and along with my old skis from a previous life...which ill never go back to. 

i was thinking of mounting the prophets in a position totally dedicated to all mountain then the watch lifes in the spot totally dedicated for park.    but im thinking that this is going to be a waste of a capable ski and a waste of money.  so could your watch lifes do everything on the mountain that i want to do with the prophet 90 and still perform in the park? im guessing yes, but i guess it comes down to where you have them mounted.  and when i said a waste of a capable ski, meaning mounting the watch life at true center when it can perform everything i want on the mountain and in the park if i mount back say, 2 from center or where ever you guys have it.  at heart, im an all mountain skier just beginning to look into the park.

i know this is a lame post and that im quite often the advocate for shutting down lame posts like this in the ski equipment forum reason being that only you can make the decision because you know yourself better than anyone else, but im stuck on this one.  

thanks.
