I have a question about my bowtech. I bought it new last year, and I've noticed when I shoot with other people that it was louder than their bows. I took it into the pro shop and they told me that they are all like that because they are "speed bows". He asked what the others were shooting and said their bows were quieter because they weren't as fast. I looked up the specs on the other bows and they were only 10 fps less than mine. Is it true that bowtech bows have a distinct sound like they told me?
