Long Distance Spec.

[joetapley]

A lot of people with your draw length would struggle to hold 38lb on there fingers.

Don't agree (most top level lady archers shoot a higher poundage). What determines draw length is arm length and breadth of shoulders. With good alignment draw length has little to do strength (not being a coach) IMO anyway.

No problem Joe, each to there own.

Go up a spine and there on after, the ACE is alway lighter than a Navigator and I suspect thinner. I know nothing about triples and have no info on the OD of Navs. X10's only good if you have lots of lb's on ya fingers.

As I said, I chose the spec for comparison, carefully...

Going up a size you get:
Triple 700s: 5.25mm 6.68gr per inch
ACE 670s: 6.02mm 5.93gr per inch
X10 650s: 4.95mm 6.79gr per inch
Nav 660s: no data, 6.6gr per inch

So... X10s the skinniest, and the heaviest, ACEs the lightest and the fattest (I don't believe 660 Navs are *that* much fatter than 710s - Beiter nock data suggests they are 5.6mm, maximum).
So the ACE at this size has the worst of it by a long way - fat and light. Of course you could counter the "light" bit by putting in a heavier point, but...

Interestingly, ACEs seem to be almost a constant size, as they go up the range (bobbles up and down around the just-over-6mm mark). X10s have a steady increase in size (seems to go up a little every other spine). Triples have a progression upwards, with a sharp step between 700 and 800 sizes. As far as I can tell from the Beiter data, the largest Nav is thinner than 6mm...

I think you are on the right track Joe, the skeleton must be a major factor in the draw length? not too many muscle bound archers about that i have seen. Good technique will provide the rest.

We then get into the question of what is better? light and thin, heavy and thin, or something in between. From a compound point of view the X10 is the best combo as there is plenty of power to move it along and it will suffer less wind drift. With recuve from a value for money point of view, I wonder now if the Nav or Triple is the best bet?

Interesting stuff.

Always the problem with 'best arrow' scenario is that you have to deal with a bunch of interdependant variables so no simple answers. That's why I got .. er persuaded into writing the drift program. It's the best arrow evaluation programme around (well OK it's the only arrow evaluation programme around outside of Easton )

http://homepage.ntlworld.com/joetapley/arsel.htm is an attempt to pull together views from a few brains on the arrow selection issue.
