I used Beldens for years at the shop and at home.The last few sets I used about 15 years ago were garbage abd arched like crazy.For a premium wire I wont buy them again.We were usin mostly Autolites at the shop and I installed hundreds of sets with no problems.I would have used Taylors there if I could of had easy access to them.When you can run them on a plow truck that sits for 7 months and only runs in snow and have no problems they are a good wire.Almost all our cars have headers with the Taylors and have never had a problem.Ill have to get a new set next year because mine are looking shabby from age.No problems with them though.Rocky
