The Warlock is a straight-up beadless Aviar copy. It flies like a beefy PnA. Great, great, super-duper underrated putter. Out of the box it's a lot like a Wizard, but it beats in more quickly (duh, no bead... )
Fun fact: The Warlock was announced as an understable compliment to the Wizard and was supposed to be named the Magic. When they molded them, they came out waaayyy more beefy than Gateway expected, but the beadless feel in the hand was cool so they switched gears and put it out as the Warlock.
The Magic when it came out was pretty different. They used that lay-down wing design that the 86 Softie had and put it on a more conventional putter top. It actually starts out a lot less stable than a Wizard, which is what Gateway was going for.
Indeed. I remember when the McPro Aviars came out I threw a Medium Warlock alongside it, identical for all intents and purposes.
