The best dumbells were in Vince's gym years ago. They were made with 7 1/2 pound plates instead of 10's. You could do a preacher curl with them and never worry about the plates hitting the bench. They were great for side laterals because of the special handles. At Gold's we had Marcy dumbbells and they were good but not as good as Vince's. I trained at Vince's in late 1968 for three months.
