Robb--You say they're not hinges- just where the wood snakes. Do you mean that part of the bow has a natural bend toward the string? If not, then they would be hinges and will seriously damage your bow and it will not last for long. If they are natural angles in the wood toward the string, then as long as everything else is bending equally, and that you are bending comming out of the fades, you should be ok. I have bows like that.
~~Papa Matt
