Here is a 9000 hour CRJ-200 pilot talking about the high roll rate.
Probably something they should address in training?

CRJ200 no fan of crosswinds

I have about 9000 hours on those wonderful little jets. Crosswinds are a challenge due to a very strong yaw/roll couple (when kicking straight after crabbing in) plus a high roll-rate for a passenger aircraft due to the spoileron/aileron combination on a short wing. In gusty conditions, you can quickly overcorrect into a tip strike.
