Replying to Freestyle/Bump ski preferences?

Im looking to buy some new skis, and im real confused about it all.. I currently have 'Rossignol 8X Oversize' racing skis, and want something a bit more rail, big air and mogul friendly.

Basicaly i have my mind set on either
K2 Public Enemys
Salamon 1080s (new models)
Head Mad Trix

Ive been told all sorts of wierd stuff, like public enemys not being good on moguls unless i reverse mount them (i still dont understand how that works, or what the tradeoffs for doing it are) also that public enemies are realy heavy (but im guesssing theyd b lighter than my racing skis none the less) ive been told that salamon 1080s are crap park skis in general but good on moguls, and ive been told that Head mad trix are way too stiff and dont have any pop.

ANy help on this topic would be great...
Im still interested mostly in the public enemys, any more info on them is appreciated, thanX!
