i use the exact same stuff. i haven't had a peavey patch cable go bad.
well, not yet. feeling ko malapit na rin. yung pedalboard ko rin kase ndi mashadong stable. darn automotive carpeting won't stick. my pedals are sliding around so much that it's either i fill it up with stuff so that things don't slide around, or tinatanggal ko yung ibang cables. hassle nga lang pag next gig.
so kung properly secured yung pedals mo, the peaveys are probably fine. kaya lang you might have a need for a longer patch.
stay away from those dinosaur patch cables. kabibili ko lang nung saken, mejo palyado na yung iba.
neutrik/klotz cables are worth it, IMO. probably the best you can find that's readily available.
