Aluminum Shaft Spine?

[ErikT]

I would like to experiment with some swaged GG II or XX75 shafting out of my recurve.

Bighorn #60 @ 27.5" draw,  
Approx. 28 1/4" to 28 1/2" arrow shaft length.

The spine charts show a 2018 to be appropriate with 125 grain point but I would like to add about 200 grains to the point with a Grizzly El Grande or a combination of points/adapters.  What would be the appropriate spine?

Erik,

Send me an email and I'll send a copy of Stu's spine calc program.  You can play with all the combos and get real close before you buy shafts.

...the next three shaft sizes by spine would be 2020,2117,and 2216. I am shooting a 60# predator with 29 1/2- 2020s and 140 to 160 up front. For 200 or more the inch less might make up the difference but you may have to go to the 2117s to get more tuning range.

Wingnut, Would you mind sending that spine chart my way aswell? Sent you a PM but forgot my email sending #2 Thanks Skippy

Follow wingnut's advice. I use the spine calculator and getting close from the start with a new bow is no problem anymore.

I shoot 2020 Legacys out of a 60 @28 Silvertip.  They are 29" BOP and fly great with 160 grain Snuffers.

I have some swaged where I just glue the head on and some are unswaged with a 38gr adapter and BH, putting the total point weight just a hair under 200gr.  I can't notice any difference in flight at hunting ranges.
