ZR and HAROLD, I have been having issues with the tie wraps breaking in the AZ sun. I suspect the UV is getting to them badly. The metal ones don't break, but I can't use those for shunt feeding, of course. Can you recommend a source for ones that don't break? It is a real pain replacing them every year or two...... He he he
