Have you considered trying to repair the broken struts. I ask because hubby successfully repaired my carbon fiver hiking pole. I have serious difficulty finding the broken spot, even telling which pole was broken. It totally snapped and splintered when I fell on it as it was held above a downed tree and large rock. My opposite leg was skinned up pretty well, but it was the ruined pole that had me close to tears. We were able to find a broken carbon fiber arrow shaft that was a close fit to the pole's inner diameter, inserted a section then used a form of 5 minute epoxy as a filler/glue, smoothing as the repair was accomplished. Send me a PM if you want to get into more detail via phone.
