I set our local club S.C.'s - most of us are retired - meaning our eyes and reactions are a bit slow . I believe anyone should be able to see any target for at least 3 seconds . And they don't have to be fast or long to be hard . On one station a slow trap is set in front of a fast one - about the time you're going to shoot the slow bird , the fast one goes by it . All our shots are within 30 to 35 yards , I just set them at different speeds . This year we stopped having NSCA events , and will hold two SXS events - just got tired of all the complaining and paperwork . Oh , and no chandeles . Paul
