One goes much more sideways than the other, but both just about get straight after 10 yards.
You'll need to view it full screen and play it a few times. It has been cut so the two fly one after the other with no wasted time waiting for the action. A better camera and loads of extra lighting would show it better, but it's not bad for a £20 E-bay camera. It serves the purpose, it will be interesting to see which flies further, my money is on the second slightly weaker spined arrow. The shoot is on July 6th, so there's a bit of a wait.
Looking closely at the video I can see the arrows show up better as they pass over the two lamps which are on the floor in front of the target. If I do it again I'll arrange some better lighting, pointing upwards.
