RE: Wood arrows
We don't like diving into the unknown when it comes to recommending a spine range. [8D] We really need to know your arrow length and pounds at your draw length.
I haven't shot 'em myself, but they say ash is about the most durable wood arrow that is easy to keep straight.
Would you be better off shooting off the shelf? I dunno. Try it and make up your own mind. I like the accuracy I get shooting off an elevated rest, but I give up some of that accuracy for the simplicity of shooting off the shelf.
Do you line up the C/L of the arrow with the C/L of the bow? Nope. The tip of the arrow should be slightly offset outboard. Left for a right handed shooter, to the right for a lefty. The reason is the string is displaced to the side when it rolls off the ends of the fingers. With the tip already to the side, it puts the tip aligned with the nock as the string is released.
Of course, then the arrow goes through paradox and all hell breaks loose.[8D]
