I read your report on the new Vipertec. Excellent report BTW! You and a few others had stated that when shooting longer distances(30-40), the bow seems to be a bit unstable...along with the Razortec. My question to you or to others is, why is this? Is it because it's so light? I know a little bit about bows, but not a ton. You might have to dumb it down for me. As I stated in a different post, I'm looking at either the Razortec and the Vipertec, but I don't want to put down all that cash without doing quite a bit of research on what bow is the best for what I want. #1..quiet, #2..smooth, #3 speed(I'd like to be around 285-300+).
