Drilled one of these up when my trusty Red Pearl Wolf started to die. Simple drilling, 11.00pin just above the fingers (I know, that's given it away, I'm a lefty) with 3/8oz finger weight and 3/4oz positive side weight. On the "Guardian" lane surface (stop wincing), it clears the heads beautifully and gives a partially rev challenged hand like mine a controllable backend reaction and is certainly easier to control than its dull black older brother. It is however a little too violent on brand new backends for my liking as it tends to leave a lot of cold 8's and 9's.
