You are indeed correct. I also conduct fly casting classes for adults and the same casting habits occur in the men as in the boys. Regardless of the age of the student, this is the hardest casting trait to overcome as they transition from lure caster to fly caster. However, once they learn that they are casting the line and not the lure, their casting stroke will begin to improve and they start to get the "feel" of the rod. It is usually the females who get this first!!
