After reading your review I have to say I'm in the first group. My hinge release is a Scott's Backspin, and I release the peg and rotate it to get to the click and make it fire. Mine is not set hot though, which is probably why it takes so long to fire.
The HBX is the best release I've come across to date, and the other five are good, higher-dollar releases. The thing I like about the HBX is I can draw back with three fingers equally, those being the thumb, index and middle finger. I pull back just as hard with the middle finger as I do the index and thumb. From there I just curl my ring finger to get to the click, then pull slightly with all four and it fires.
I'm firing my shot in four-five seconds typically from full draw against the limb stops to releasing the arrow. It seems like longer than that and my single-pin sight begins to wander. Once I get to full draw, I relax my bow arm, which settles the pin on the target, while exhaling like I would using a scoped rifle. At the bottom of the exhale I've hit the click and a second or two at most later off goes my arrow.
I've shot about 500 arrows with my HBX and it is my favorite release of all time. I feel very fortunate this design came along, as it fixes what was missing for me and it is second nature to use it. The more I use it the less I even think about it, as I am able to instead concentrate on the target.
