I shoot wood and I can say that they are easier to for me to get set up.And they feel natural to shoot.
And accuracy is in the shooter not the arrow! you can have the best most expensive gear,and if you don't have good form and can't shoot it won't make a difference what arrow you use.
Think of the natives in New Guinea( I may have spelled that wrong)they use unfinished branches and a leaf for a fletching and they can hit a monkey jumping from branch to branch with ease.Not with carbon or aluminum,but a branch!
And thats all I have to say on that-Forrest Gump
