see my post above. My little kiddie niece did a total number on the aluminum poles. I didn't think she could have done anything similar to fiberglass, though now that you mention it...it's entirely possible.....It seems that fiberglass is more resistant to crushing than aluminum......But dome poles and similar tent poles are rather fragile no matter what they're made of.......The repair sleeves are apparently a temporary solution. Not a viable long-term repair I don't reckon.........

I fully appreciate weight advantage of aluminum poles. (Not really sure if they offer other advantages.) Hence I replaced them at a cost nearly approaching value of the Eureka tent. It was a four-pole dome with non-total fly coverage. Weighed about 8-9 pounds. Certainly not a great tent, but it worked good.

Killed by mold after about 20 years as result of pine sap and brief lapse in loving care. Poles are currently fine but not useful.
