What alum is equivalent to 600 spine skinny carbon (eg Carbon One)?

What weight point and insert are shooting on the .600 and do you mean dynamically equivalent or statically equivalent?

JTK -

1916 at .623. (Remember an aluminum arrow will act weaker than a thinner C1.)

Viper out.

Fdp...dynamic Viper...so I'm guessing 2016..

a 2016 is a 500 carbon equivalent

Pretty sure I saw my 2016 are a 500. So 1916 I think is correct. Good for around 40# bows

What kind of point and insert weight are you shooting?

.600 is a static deflection number. As Viper eluded to, the dynamic reaction won't be the same due to diameter and material characteristics.

Your best bet with aluminum is to base your selection on actual draw weight, arrow length etc.

The above are all 'close to .600' but will all shoot differently due to weight, diameter etc.

In my experience 2016 's cover about the same range of draw weights for my various recurves as does a 600 carbon.

1820's are one of my favorites.

Carbon also resists bending more than aluminum, and recovers quicker on the shot, so even the same static deflection won't react the same between the two using the same tip weight, arrow length, etc. Beg or borrow some single shafts and test them for yourself....it may be an eye opener and will teach you what words can't.

George is correct, that is why guys front loading aluminum wonder why they are hard to get to fly right. Shawn

George x3 words of wisdom & years of experience spoken again. Listen to this gentleman.

Have found as mentioned above that aluminums act Significantly weaker compare to carbons.

Even same spine carbons from brand to brand tune differently in my experience.
