I would be buying "factory direct" but you have to "check with the manufacturer" as to the composition of the hose inner liner? What a load of hooey.
Skieved hoses? Speaking strictly from practical experience and not from formal education on the subject, I would not knowlingly buy skived hose assemblies. Compromising the outer layer by skiving will do nothing but shorten hose life by allowing water and other contaminants to degrade the wire compopnent of the assembly as the outer hose layer does not extend to the butt of the crimp.
