Replying to Suggestions for park skis

im looking for a pure park ski, don't really care about all-mountain performance or powder cause i have hellbents for that. probably be doing 60% jumps 40% rails, won't be hitting any jumps above 60ft. previous skis i owned were 07 rossi ghettos and 04 rossi scratch pros. i liked the flex on the ghettos, it wasnt to soft or to stiff.  dont really know if i should get a symetrical ski or rockered. is it better to have a symetrical or non symetrical?

Weight:150 lbs   Height: 6 ft

i have looked at:

atomic punx
moment rockers
line anthems
armada alpha 1/2
amplid antidogmas
corrupt  TJ pro
ON3P BS

thats my list so far. feel free to add on.

thanks for the help
