Karlyn plug wires?

Has anybody ever used Karlyn plug wires for their Aurora? I have ACDelco's now, but they need to be changed. I just had a Karlyn set, #769, bought for me, a birthday present, for my 99 Aurora and was wondering about their quality?
Their web site link is http://www.karlynsti.com/Folders/Karlyn_STI_Ignition_Wire_Sets.htm (http://www.karlynsti.com/Folders/Karlyn_STI_Ignition_Wire_Sets.htm)
Thanks in advance, Bob

Was put off by the description of the red wire.....even the cheapest ignition wires use right angle metal connectors......
