When I originally started out grappling I forced myself to only used butterfly guard. Why, cause no other big guys were or could do it. So after getting my guard passed and being smashed thousands of times I actually got pretty good utilizing butterfly hooks. Now do I recommend this approach to other grapplers - probably not. There are other much easier ways of learning sweeps including visiting our site and checking out Chaz of www.Lockflow.com. Today he demonstrates the position he calls the "Hook Guard" and how to execute the hook sweep he calls the Rollback.
