The Warrior Burn is hands down the most underrated lacrosse head on the Warrior line. If you taked a closer look, this head is almost identical to the Warrior Rabil 2. It has SYMRAIL technology that shaves the inner sidewall to match the outer sidewall to reduce weight without sacrificing performance and durability.
Warrior also implemented a recessed sidewall which moves the stringing holes adjacently away from the inside of the throat to reduce the likelihood of an Illegal stick penalty without sacrificing pinch. The only difference between this head and the Rabil 2 are the sidewall design and the Rabil 2 is built to be a little more durable.
