I have Great Northern and Eagle Flight. I use the GN for hunting because it straps on great to a longbow and is totally silent. It does not strap so great to a recurve because the limbs are swept back. I mounted one to one of my recurves by bending the wire arms 90 degrees and strapping it to the side of the riser.
The Eagle Flight is a very small package to go in my hunting gear as a backup. Since it mounts to the limb it flexes with the limb and about every 3rd or 4th shot the back arrow comes loose from the gripper. It's a pain for everyday shooting but for hunting where you only take 1 or maybe 2 shots, it's a non-issue. Also, on some of my bows the top portion tended to walk up the limb, but on other bows it stays put. Again, a non-issue in hunting, and it saved the day for me once when I needed a back-up.
I recently got a Kanati adjustable side-mount quiver, it straps to the side of the riser and fits every bow I've tried it on except the Howard Hill, the riser is just not wide enough for it on that. Also, when you order it you have the choice of small, medium, or large gripper. Where with a GN it only comes with the large gripper and you have to buy an additional small gripper if you are going to use carbon arrows.
