I need some opinions, this should be interesting!

I'm currently on an '02 AC ZL800 and looking for a new sled. I ride with two friends, one on an '07 AC F8, the other just bought an '08 Yamaha Nytro. We ride in upstate NY, almost exclusively trail riding, mostly groomed, but will ride some rough trails from time to time. Never mountains or fields. What sled should I be looking at to keep up with these guys? I'm not too concerned about manufacturers, just looking for handling and reliability, and of course power! Thanks.
