Im still going through my IAF training right now, but I have a chance to get a used chute but I dont know if it will work for a begginer because its a CRW chute. Its a 1990 Precision Interceptor 250. I weigh 200# right now. I was just wondering the difference between a CRW vs. a Non CRW chute, and if this would be a good purchase for me. Thanks for the help.
