Replying to Longer skis in park?

Hey was just looking for some opinions on ski length (/weight) in park.

I'm on some 158 Rossi Scratch Pros and haven't really had any complaints but... I'm gonna be giving them to my friend who I've wanted to get into skiing since forever but he really doesn't have the money to get started so.. I'm hooking him up with a pass that's attached to my employee pass, he was able to pick up boots and I'm giving him my Scratches.

SO, long story short, I'm gonna be looking at some new skis that I'll use on non-pow days (grooms/trees/moguls etc) and to screw around in the park with.

I like that my scratches are so light, makes it easy to learn new tricks (practically can't feel them half the time) but they're the only thing I've ever rode hard in the park save for some demo Extremes which were pretty legit.. but I just don't have the experience.

Opinions? How do you like your park skis to be? Short and quick or more weighted and stable? If it's a specific ski you point at, I'll go dig around for reviews and stuff on em.

Thanks for the advice
