Hey Holt, I am finally decided to join a roller hockey league in the summer. I am not the best skater nor player, but I enjoy playing. I'm sure if you join, many people will be on the same boat as you. There are going to be some teams that seem insanely good, but if you enjoy playing it, than why not join.
Do you have full equipment? I'm talking helmet with a cage, girdle, shin pads, elbow pads? Some leagues if they're not check, do not require shoulder pads. This is a great website where I got all my equipment for an amazing low price: http://hockeygiant.com/
Go to their clearance secton; they have so much great equipment for nothing.
