As someone relatively new to Reflex, where should I start? What videos, communities, players, or other sources should I watch, look out for, contact, become a part of, etc?

Is it possible to learn movement with a relatively low sensitivity? If I', able to do a 180 in either direction without lifting my mouse off my mousepad is that enough? What are some good maps for just messing around to get comfortable with moving?

As for aim, any recommendations on becoming better in this regard?

I'm curious if anyone uses RInput with the CEVO client? And how would you set that up?
