Thanks Nubbb, I went to the Tasco website and was checking out the PDP3. What do you think of the Tasco BKRD series of red dots? There are 4 variations of scopes. Is it worth adding an ounce or two of weight to get a larger objective lens diameter. Like the PDP3 you recommended has a length of 5" and weight of 5.5 oz. and a 25mm obj.lens diameter compared that with the BKRD42 with a length of 3.75" a weight of 6.7 oz. and a obj. lens diameter of 42mm, both are by Tasco which would be better for a bow given these stats?
