Could these be used to brace a fibre glass pole that has split? I 'repaired' a fibre glass pole with some duct tape a while ago but I'm expecting others to go sometime as the tent is a few years old now. My daughter is away with the tent in the Peak District ATM and I did think of her when it was pissing down yesterday (hopefully the weather was better up there). I'll see if the poles are 11mm when she gets back
