Replying to Need help choosing skies

Hi there, I have decided to pick up a pair of twintips. I have skied for awhile, raced for the past 4 years and have always loved getting big air, doing tricks and much more but have never had anything other then some racing skies. I am a pretty strong skier and would like to get into park skiing but still be able to ride everything on the mountain. So i guess im looking for an all mountain/park ski. i have no idea what to buy, so far i have looked at the 4frnt MSP and STL.

I currently have a pair of rossignol 9s 165 and rossignol 9x 185. I am 6'1 and weigh 160. I'm not really sure about what size i would need for my skis because i have a short pair for slalom and a long pair for GS, so I'm sort of unsure where i would be for a twin tip ski.

Your help and suggestions would be greatly appreciated, Thanks.
