I shoot Axis arrows at around 295 fps. I use blazers now as well. They are lighter so my arrows are faster. They provide less drag so that my arrows maintain their speed better down range. The high profile of the blazer provides adequate stabilization for my setup. I shoot mechanical broadheads (Wasp jak-hammer, GR razor tip) because I believe they are more forgiving in windy conditions. Therefore, I don't need as much rear stabilization as a fixed head that might plane in the wind.
