I've such discovered a new sight at the Harrisburg sport show, it's by www.viperarcheryproducts.com . The new Predator line and the newest not on their website features microadjustable knobs....very impressed. The black retails for $149.00 and will be the sight on my new bow....this sight features a hamonic dampener built in, 7.5 inches of fiber for brightness in .029, .019 or .010 pin sizes....machined aluminum and stainless steel pins...very sweet.
