They pretty much said that your arrow isn't going to drop fast enough at such a short distance to warrant a pendulum sight.
Good advice from whomever those pro's were. Set a single pin for 25 yards and then see where it hits at different distances. Assuming a modern compound bow and shooting most whitetail scenerios you'll find about a 4" drop at about 33 yards, 2" high at 20 yards.
Assuming a normal sized deer with an 8" vertical vital you should be able to hold mid-body on anything within 30 yards and just shoot.
This negates the need for a pendulum sight with moving parts and the extra noise it may make. Plus, if it's good from up in a tree then it's of little use on the ground.
