I have the Predator "slide" sight from Viper. I really like it. It was so bright, I actually covered the fiber tube with black shrink tubing to dull the pins for me. I love the .010" pins too for my 30-50 yd shooting.

Interesting. My only complaint agains my Hunter Hogg-it is the brightness under low light. I actually bought the sight light but found it was too bright. I have some tape on there to cut down the amount of light going to the pins.

Thanks for the heads up you guys. I will have to take a closer look at the Viper sights.
