The main reason I went from a 5500 to an Eflex 3 600 break glove was the difference in protection and size between the two. Vaughn's equipment is well made, but has always been on the slimmer side. I didn't feel confident enough with the protection the 5500 had to offer, even with a pro palm. Even with a stiffened T and not pressing down on the T like a lot of people do, it would cave in on me on a regular basis when making a glove save. The Eflex 3 glove is the complete opposite - beefy, T closes well, and is much bigger in size. I think Vaughn's pads and blocker provide adequate protection and their pads are nice because they are so bendable, but most people go with a different glove because their gloves do not provide enough protection and break down very quickly.
