I haven't tried everything but from what I've used I'd say:
Shoots (I've never had one break)
Ocean Spray -because it's plentiful in the North West, tough as nails, stays straight.
Indian plumb -plentiful, tough, stays straight, real easy to clean and straighten
Wild rose -plentiful, tough, stays straight (painful to harvest and clean)
Shrub in my front yard -plentiful, tough, stays straight, real easy to clean and straighten, light weight
(Sorry, I don't know what it is, just makes a wicked arrow)
Garden stake bamboo -although bamboo, I've noticed these vary in type. All tough, stay straight,easy to straighten
Split timber
Doug fir -stays straight, pretty tough, plentiful (only one I've tried)
Don't like any shoot that is in its first year. Too flimsy.
Aluminum doesn't shoot well from my self bows
