I have what I considered to be an "expensive" family, general use tent that came with fiberglass poles. After very little use and none of it in high winds or snow loads, one of the poles has split. I was able to temporarily fix it with some duct tape so that it didn't damage the tent material but it will need to be replaced. I haven't spoke with the customer service department yet to see what they say so I will refrain from posting the manufacturer. I would like to upgrade to alum if it would be worth it but I'm not sure what new poles go for yet.
