I'm thinking about switching from carbon to aluminum arrows. My current setup is 60" recurve, elevated rest 47#@28, and 64"longbow, off the shelf,44#@28". I have a 28 inch draw. I'm currently shooting GT3555,30.5" with both bows different weights up front. Stu Miller helped me set my arrows up.I have tried to research my questions on here and other sites but some questions I can't find any info. So here goes:
1. On Stu Millers calculator he has Gamegetters listed with spines and Alum #'s with X7 after them. Does the X7 stand for XX75 easton arrows?
2.What is the difference between arrows that start with 19, 20 and 21? I believe this is wall thickness but can't confirm.
3. With me currently shooting a 500 spine carbon arrow should I stay with a 500 spined aluminum arrow?
4. Are the XX75 Gamegetters and the XX75 Camo arrows the same with the exception of price and weight tolerances?
I appreciate any help on this. Thanks.
