I've been hunting with an Excalibur for a few years and used a drop-zone on my Vixen, and a vari-zone on the Exocet. Both are excellant scopes providing aiming points out to 50 yards. But.......
I have also in the past few years been known to get a bit brain dead when a deer shows up, and although I know the distance (pre-determined with a laser rangefinder) I revert to using the crosshair (dead on @ 20 yards) instead of the correct yardage mark. This mental lapse has cost me a couple of deer by shooting under them at just over 30 yards. So.....
I bought a 2X magnification red-dot scope! Sighted in at 25 yards it puts all my arrows well within the kill zone of an adult deer out to 30 yards this way. I can hold a little over/under for precise shooting if the target is closer or farther than 25 yards, but if I forget when shooting at a deer it shouldn't matter. The trade-off is that much beyond 30 yards trajectory makes precise shooting very difficult. The 380 grain arrow @ 300 fps actually drops about 11 inches at 40 yards, and I quit there
As for a quiver, I tried an Excalibur bracket and just didn't care for it. I went to a hip quiver and it works fine, but I decided to try one of Dan Millers brackets and it's great, too! I did slightly modify it (turned it "backwards" to get it further away from the front sight) and added a couple more screws (I drilled & tapped) for more rigidity. The quiver that came with it started making a bit of noise when I shot, so I stuck an old PSE quiver I had on it, and it's very quiet.
