Im toying with aluminum arrows. And depending what chart i look at im pointed in different directions. Some charts say 1716,1816, 1916,and 2016. Im shooting between 30-38lbs, 27" arrows. As a side note, ive also been toying with 1820 nasp arrows. I have no clue how nasp shooters can get those heavy shafts to fly right, even out of their low poundage compounds, wow.

Brian -

Assuming a standard recurve and 29" arrows/nominal weight heads, 30# = 1716, 38# = 1816, break point is around 34-35#.

1820 "nasp" arrows were sold to be shot with Genesis bows, set close to center shot. Flight is never perfect, but with brats, you have to weigh flight with durability. Yes, a 30" 1820 = about 50#.

Viper out.

I was just a range official at a NASP tournament and I saw horrible arrow flight out of some kids and great arrow flight out of others. Seems the 6'+ boys with long 31" and 32" draws got a horrible flight but the smaller kids got good arrow flight. Those Genesis bows may be compounds but they have no let off and are 20# bows.

reddogge, if you overspine a bow enough, it will essentially remove the paradox and the arrow will fly like a missle instead of, well, an arrow.

reddogge, they are cut well past center. At 20# since they alread are at center, they don't need to bend and there isn't enough power to force a bend on them. . Centershot...where the arrow rides in the center of the bow...there is no need for spine. The big kids were just pulling them further and applying more weight to the arrow over a longer distance. And frankly, you can't make one arrow that will work well from 24 to 30 inch draws at different weights from the same bow.

NASP arrows are made to take bad shots yet fly well enough to hit the target. Try those so-called kids arrows out of a 50# bow at a 28" draw...29" arrow and you will be closer to tune.

Easton chart

this is the one I use for recurve bows

Here is a link for Kelly's arrow chart that works real well. www.arrowskp.com

Stu Miller's spine calculator works well for me. There is a similar calculator at the 3Rivers website. I like the calculators because I can build a "virtual arrow" (or several) that will be pretty close to spine before I plunk-down cash for a set.

I use 3R’s calculator as well. It’s a good start so far. But be cautious you can get more than a couple possibles by changing one or two inputs. Know all the info it asks for sure. Guessing at an input can change the results. Been there done that.
