Long Island v. NYC Derby

I'm a graduating high school senior, and I am going to college just outside of NYC on (towards??) Long Island. I want to join an adult league in college (currently in a jr league), but I don't know which one to pick. I'll be about equal distance from the Long Island Roller Rebels and Gotham Roller Derby. I am more familiar with the Roller Rebels, because my home team has played against them and some even used to play for them. However, they don't seem to have as much basic training as Gotham Roller Derby. On the other hand, Gotham also doesn't seem to have a permanent practice space, as the first thing that shows up on their website is talking about how they don't have a place to practice. They both have pros and cons and I don't know which one to choose, please help.
