Great replies!
If I' m understanding Bucky Fuller right, he tells us to leave a nerds point of view. Master bowyers, as other experts too, are often "to business as usual- minded".
As posted above, there had been hundreds of topics and discussions focused on designs, capablities of woods, strings, shooting techniques, arrows.....................etc. I guess Bucky Fuller's method is to look at first at the whole thing, not its details. I think this is hard to do, cause we all are educated to become or to be specialists.
There are a lots of great bowyers, well and clever done bows and perfectly matched and beautiful looking arrows out there, why not to try to outperform Tim Bakers 200f/s challenge?

I try to focuse on the exceptions. Some month ago I came across a chrono- test during the weekly training of a primitive archery community. There was a 70lbs osage longbow vs. a 48lbs BL- bow, same arrow, the BL shots the 270grs. arrow at 174f/s, the osage at 158f/s. I checked the BL- bow: a very well done flatbow, parallel limbs, skinny not to long tips( modified molly), so far nothing special. But the BL itself looks to be extremely dense, very dark latewood. The bowyer told me this BL was the the hardest BL stave he ever had come across.
What makes a stave better than another stave of the same wood? I guess we' ve cared to less of the indications of real great staves.

Steve, I know of Alans outstanding arrows, but I' ve never had a number, this "big fat 100 yards" is indicating a very weak spot.
Did you know the spine of Alans arrows?

By the way, whats the highest possible spine with wooden arrow- shafts?
I' m still thinking that the capablities of an arrow- shaft should be better defined by spine/mass. The term arrow- spine tells not to much about the weight of a shaft?

I have not dared to enter the world of flight shooting yet as I am not ready, but I have always wondered about this, spine versus mass.

I'm beginning to tinker with flight shooting and looking towards that 200fps from a self bow.
I think getting the right spine rather than just stiff for the hell of it is important, but a good loose is vital, maybe that's the weak link.
Obviously a 1/4" diameter arrow has a smaller cross section than a 5/16" but if they are barreled over a long distance front and rear how much difference does it make? What I'm asking is... Is the aerodynamics more important than the cross sectional area? I've seen some "flight" arrows with the points very poorly blended in. And I think it's easy to forget the aerodynamics of the nock end too.
My big prob' is lack of a safe testing area.
Maybe one of you guys can PM me a quarter mile of prairie so I can unroll over here to give me a practice range ;D

Like Badger i believe the arrow is the weakest link.
But i think flightshooters are better than most as they deliberately works on it.
Many times you se someone put blood sweat and tears in making the best bow they can or twaking the newly bought bow and then grab "some" arrows to shot.
Tweak and trim your SYSTEM..not just the bow!

Just my 2c  :P
It's better to ask and look like a fool than not to ask and remain one...

"I would say the limbs.
The string is overbuilt.
The arrows are tuned to match the bow",
Lostarrow, you need to see my set before you say that  >:D

Flightarrows have to be barelled, thats the aerodynamics. Cross- section is largest just around the middle(center of gravity) at about 1/4"- 5/16", nock at about 13/64", tip at about 5/32" or less. Have a look at Osmanian flightarrows, perfectly blended in nocks and tips. Have a look at Alan Case' s flight arrows: http://paleoplanet69529.yuku.com/topic/29783/Split-Cane-Bamboo-Flight-Arrows?page=1, highly recommended!
Yes, even the best flightbow is just 50% of the whole challenge.
