ok man, heres my advice. for your sive and weight, the prophets are a bit on the short side. but that is a bit stiffer ski, and not a full twin (i believe), so its prolly ok for all mountain.
so you have a couple options.
1. keep the phophets, and buy a cheap park only ski
2. sell prophets and get 1 do everything ski
depending on the condition of the skis you have now, i would recomend a cheaper park ski. this season, i recently got a pair of silencers, with the intention of it being a hold me over till the 08 4frnts came out (i kinda ride for them, its wierd). anyway, the ski blew me away. wicked fun. i too am not a big fan of the current public enemey, however, the older one, which the silencer is based on, was great. its a fairly stiff ski, but it does break in a bit. im 5'10", 155, and can butter them easily enough. and its very very poppy and energetic. not to mention they are DIRT cheap. someone posted a link somewhere, they were like, 209 or something, thats cheap. the cost of those skis is 151, so the retailer only makes 50 bucks on them, and thats as cheap as your gonna find them.
its a pretty good all mountain ski as well, but its a little chattery due to the cap construction. but as a park ski, its great. get the 179, obviously, and mount them at core center, which actually is a few cm back from dead. get on ebay, and snag some p12s. it can be lifted or whatnot, it doesnt matter (pull the plates off). those can prolly be found for 100-150 new or slightly used. there you have a sick park setup for about 300 bucks, and thats as good as your gonna get.
