Replying to Summit or Rocky Mountain pass?

It's my first season here in CO, and I don't know which pass I really want to go for. I'm more of an all mountain cruiser, enjoy rails, but the park is more of a back thought (thanks to the knees). I'm also in Boulder and don't know how the traffic goes, and convenience of access is definitely a factor for me. Any info will be appreciated +k, the price hike is looming a week away i believe. Also I'll be looking for carpools and crews to ride with since I'm new here.
