Yes, I am using the HHA Optimizer Ultra and it is Awesome. I used it in NE on my recent Mule Deer and Turkey hunting trip in Dec. It worked very well in the field, and it was quick and easy to adjust. I will have one on my Airborne when it arrives.

As a matter of fact all my hunting bows will be sporting these sights before next hunting season. They have impressed me that much.

Anymore I prefer a single pin rear adjustable sight. For Multi pin sights I still think the Spot Hoggs with the new wraps reign supreme
