well as for what bolts to use, I would honestly use the maker of the X bow, as this way you know they are made for your x bow,
both the X bow makers you listed have bene known to shoot 22 -24 and 20 inch bolts
and all make x bows of all different draw weights
thus when they sell a X bow in a package, they have bolts made just for that bow,
NOT saying you cannot match up other makers bolts
but since costs are so close, why bother I say
as for scopes, same deal, many have the hash lines set to match there bows,, thus meaning being a little different from brand to brand name Spec's
I like the reticles that can be light up, and even change color
and still have the standard Black , so in case if a battery dies, your still good! in Low light the lighted reticles are sweet, BUT make sure there is adjustable brightness, or they can be over powering, defeating the benefits
