Try em all and then go with what you like. That'sthe bottom line. That's what I did and I use nothing but reflex non magnifying sights. Single dot use for 35 yards and closer it's The Zeiss Z-Point....expensive but worth every penny. Another good single dot holo sight is the Pride Fowler.Nothing else is even close to the Z-Point as to versatility, features and being bullet-proof. For 3 dot sights for shots out to 70+ yards, I use Ten Point and Stryker sights. quality is not Zeiss for sure but they are the only games in town for 3 dots that I would use. I tried a Truglo holo and it does not measure up. Sorry:-( I see no logical reason to use a heavybig bulky rifle type scope on an already heavy close range crossbow. If you do, have at it:-) JMO
