STX Hammer U
Looking for a new shaft can be difficult because there are so many good ones out there to choose from, but when it comes to choosing what head to use, in my opinion there is only one top of the line defensive head. The STX Hammer U. This is what head I've used on my stick the past 3 years and I plan to keep using this head until they put something better out, because right now this is the head to have for close defense. I won't bore you with all the details, but my favorite thing about this head is how stiff it is. The guy in the video below shows how other heads can be easy to bend back and forth but the Hammer is near impossible to bend when you get it. The benefit to this is that it makes your slap checks, poke checks, and trail checks (and yes there are more) all harder so you have a better chance of getting the ball out, and who doesn't like causing the offensive player a little more pain? I could go on forever about how much I love this head but if you really want to learn more about it, watch the video below, he gives a great review on the head.
