I like 90 degree 4 fletch, personally. But if you're brand new to trad I really don't think you need to worry about fletching orientation or bareshaft tuning till you have at least a couple thousand arrows through the bow.
Just fletch all your test kit the same and shoot the whole batch for a few days, making notes on which spine of of arrows fly best. You're gonna need more shafts by hunting season anyways.
