PA Hardwoods:
Sorry some of the responses you got made you feel like you were being attacked. From my personal opinion, it has everything to do with the STS discussions on ArcheryTalk, and absolutely nothing to do with your post. Over there, if you so much as question some rather outlandish claims by enthusiastic users, you get clobbered, and your character questioned.[:@]
Now, on to Dave's question about broadheads. I had stated before that I thought my bow was a little more accurate without the STS. I really think it was, but since I had the STS on the bow, I have fine tuned the rest. I thought the STS changed my POI a little, but again that was before last week's fine tuning. I'm not going to go overboard here, but I can be pretty confident in saying the STS did not have ANY negative effects on my broadhead flight or accuracy. In addition, my POI did not change after I put the STS on the bow, as it had before. If, as I wondered, it causes any downward nock travel, it didn't seem to have any effect. It seems doubtful based on how my arrows were flying. I apologize if my previously posted misinformation clouded this issue.
When a 53 yr. old with new progressive bifocals can shoot the way I shot the last 3 times out, life is good! (At least until the wife wakes up.)[8D]
