Thunderhorn = quiet, strong, well built. Downside is it's very heavy. Great quiver, that's all I used to own, had 4-5, one on every bow. Now, I only own one. Great folks to order direct from, they work very hard to get it exactly how you want it.
Eagles Flight = quiet, strong, well built, light. For me, the substantial weight savings coupled with a very simple yet effective design makes this my favorite quiver. Downside is they only hold 4 arrows...that's the only reason I kept the one Thunderhorn. Don and Karen Ward are some of the finest folks you'll ever do buisness with, providing both superb products and customer service.
