Is spine the same?

[swamprooter]

Maybe a stupid question but what I am asking is, will arrows made of different materials that are spined the same fly the same? Thanks, Chris

Nope, there are other variables involved.  Density and weight make a difference, as does diameter.

Trajectory would certainly be different,due to differing arrow weights.I also shoot a heavier spined wood arrow than aluminum off the same bow.My experience with carbon leads me to believe it can be a bit picky regardless of correct spine.Don't know if I answered your question or not, but I think every arrow type is a little different.

Thanks, that's what I suspected, I have a bunch of river cane drying in the garage and just wondered where I need to start with them. Think I will spine them the same as my 2016s and take it from there, may have to go a little stiffer or weaker just have to experiment. Chris

A heavier shaft will require a bit more spine..................cedar 55# shaft compared to hickory 55#shaft; cedar will fly stiffer than the hickory.

Interesting..
I thought it would be just the opposite as the lighter arrow would get going faster and get "snapped" more.

Good to know.

The heavier arrow accelerates more slowly after you drop the string, absorbing more energy and bending farther than the lighter arrow.  Takes more spine to combat this.

not arguing the point.
Makes sense when you think about it.
Just as with many things..my gut reaction was wrong..lol

Nope, that is why carbon is so different than all other materials. It recovers very quick and you can get away with a lot lighter spine than most people think, Even carbon of the same spine will fly different due to diameter and the weight per inch of the shaft. Shawn
