wouldn't such an experiment be a bit inconclusive. You chose a design to fit the wood, because they have different properties meaning that any single design will inevitably favor one type of wood over the other. And since they are different woods how similar do we think the dimensions could be (presumably osage is going to take quiet a bit less wood to reach the same draw weight as hickory) and how that might impact results. btw I'm not against this idea, but unless it shows a very clear difference it may not tell us much about anything except how those species preform in that one design
