plug wires worth a $#!T?

was scouting Ebay and saw a couple of sets that say theyll fit something I have taht I need wires for and price didnt seem bad....
Anyone use MOROSO plug wires?
How bout Split Fire "Twin Core"? I know I wouldnt give a dime for Split Fire plugs.....
the ones I see are an 8 mm insulation size which in and of itself cant hurt...
Incedentally both sets I am looking at are for a slant 6 with "peanut" plugs ('75 or newer)
