STX Hammer U

by - verified purchaser From RICHMOND, VA
I Absolutely love this head. Stiff, durable, and wide. Everything you want in a D-head. Although it would've been cool if they put ACP in it, I think this head is durable and stiff enough to go without it.
Pros:
Stringing holes, C-channel Tech, Stiffness, wideness, two screw holes, weight, matte-like finish to the head
Cons:
Not really anything

Quality Buy

by - verified purchaser From GREENSBORO NC
Great overall head, one of the best on the market for the defensive position. The Hammer U features and over all more polished and advanced design than the X10 or newer heads from competing companies. Worth the Price!
Pros:
Great defensive head with heavily reinforced side walls. Very stiff head, this thing is rock solid and very hard to warp. A great pairing with the STX Stallion Sci-Ti
Cons:
Could be a little more flexible for ground balls, you will have to get used to scooping with it. Very hard to warp, however steer clear of darker colors. My teammate has a black one that warped slightly int eh heat. Could be more pinched however if strung rite is still great for LSM.

Have used better

by - verified purchaser From WESTMINSTER MD
This head is very stiff. Doesn't have the flexibility that is advertised. Bent within the first week of high school season. I will not repurchase this head in the future.
Pros:
Durable in cooler weather. Makes poking and checking possible without breaking
Cons:
Needs better flexibility.

Not Worth The Price!!!

by - verified purchaser From RI
Good head, but for the price, its not worth it unless you want a head that's going to be good for a month then warp to the point that it's unusable.
Pros:
This head was really light for the first 3 weeks i had it, it was stiff. Really durable, no matter how I bent it, it didnt break. Also really wide if you like that
Cons:
one of the most expensive heads on the market and It warped so bad that i had to stop using it after 2 months. Also became very flexible after about a month
