Suprised by your arrow turn out?

[9 Shocks]

Have you ever bareshafted an arrow for a bow and come out with a suprising comibination?

I was bareshafting arrows for a 48@26 centaur longbow and the arrows that seem to fly best are 29" 1916's with 200 grains up front!  It seems way weak by my approximations but they are flying well.  2016's full length with 145's also flew well.  Any have experience with this, where they were surprised to find out what the bow liked?  I have found the majority of my bows (5 so far) except for one liked a weaker arrow (by roughly 10lbs according to stews calculator).

Yes.  The more I've worked on my form and incorporated Arne's video tips into my shooting (Moebow 1 on YouTube), the weaker spined arrows I've ended up with, for some reason.  I am also shooting 1916s out of a 45lb recurve that are 28.75" long (not quite 28" draw, but very close) with 150 grain points.  I have also put Woodsman broadheads on them and they shot exactly like the field points, so I feel confident that this spine is correct.  I played with carbon arrows and was thrown by the fact that everything seemed overspined till I got down to CX 75 arrows, which seemed like they must be too weak.  I found that aluminums were much easier to tune, personally.

A good release can get you shooting a weaker arrows sometimes.

Same with me. By Stu's calculator my arrows are way weak but they fly well so thats what I go with.

I have a theory that length has a much bigger effect on spine than point weight so once you get the length about right you can add more point weight than seems likely.
