By the way, I mentioned that I have an HHA sight, but I didn't mention that I changed the aperature (last summer) to the Impact model with the glow-in-the-dark tape under the fiber-optic coil. It is BY FAR brighter than the original pin. Although, the HHA is about 7 years old now, and sights have come a long way since I made the purchase.

IMO, the glow tape in one of the best ideas I've seen on the modern sights.
