A guy I know at the range had one for sale for $350. I don`t really care for recurves at this point,but figured $350 was a good price and asked him to bring it down so I could test fire it. Anyway,,the bow had a lot of vibration after the arrow was gone. This was with the dacron string..so we changed the brace height all over the map,but it didn`t seem to do much. We then changed to a Fastflite,and we had pretty much the same results.. Are these bows normally like this,,or is odd for it?
