Third question - why those two arrows are so special? Have you compared them to similar arrows, which are not so good? Is there any kind of measurable difference? You have made a lot of split cane arrows but what makes some of them special? Spine, weight, diameter, balance point, some parameter we don't know yet.

I heat treated some Sitka spruce shafts in an oven set at 375 degrees f for just long enough that the color of the wood began to darken a slight amount. The stiffness of these arrow shafts were incredibly high afterward, which is just what I look for in an an arrow shaft material. Unfortunately, much of this benefit faded away over the next week as the arrow shafts regained moisture.

I will have to carefully look through all my flight arrows to see if I notice some traits that the best arrows have in common.  It doesn't seem very obvious to me right now.

Tuomo:
It is very interesting that one arrow functions well with 35, 50 and 70# bows. It seems that fine-tuning of bow-and-arrow is not so important. There has to be something else.

If release is good and arrow is leaving bow well and supposing that speed is same between different arrows, then the only discriminating thing is how the arrow is flying. We can measure speed of arrow, see how it is behaving at release but don't see how it is flying. Maybe there is something what you said about landing angle.

Badger:
  A good arrow you can't see at release at all they just disappear. Any arrow you can see is a bad shot it seems. About 320 yards is the maximum I have ever gotten for an arrow I could see leave the bow and track for some distance.

That disappearing arrow obviously leaves the bow cleanly and fast. BUT that doesn't mean it still can't have too much drag to slow it down and fast. Right? Not that it would be the case everytime, but just as a minor point.

I think those arrows Alan Case shoots from 30# to 70# pound bows, can't possibly leave all of the bows super cleanly (because of different spine), but still maintain their flight for "quite" :D long.

Perhaps the tapering in the rear half helps more than one would presume?, although that's quite a bit of range.

Alan, in addition to citing the poundage range you have had good luck with, could you comment on the handle widths of the bows in question?
