RE: pendulum sight
I bought a Tru glo pendulum on ebay for about 33.00. After setting it up and testing it out, it works pretty well. My max dead on range is about 36-38 yards. At 40, if I aim near the top of the vitals, it hits close enough to get the job done. (basically drops about 3").
As far as how quiet it was......my dad was standing under my treestand about 20 feet under me and said that the arrow striking the target 30 yards away was louder than the bow going off.
