I really like the brine edge for a defender, being a defender myself I needed a really strong reliable head and this is one of the best If you aren't trying to go broke.Pros:
I like the stiffness and the ability to customize the pocket because of the many sidewall holes it has, The brine edge is an all around great defensive head but it is also a great attack head. I like how it was very cheap and I didn't go broke after buying this.Cons:
There's not that many things to improve because it is already great. Probably the only thing I didn't like was that it didn't have a second screw so it kind of rattled whenever I threw or shook my stick.
