Can't really say I prefer any brand wire...Firecore makes what is probably the quietest wire out there, but again I would say your MSD wires are probably not the cause of the problem just yet. So you're saying the strobe is on all the time never flashes? WOW that would require A LOT of noise, any chance your coil wire is near where you're hooking up? that one is hot nearly all the time with engine running. I'd try seperating the wires out as far as I could, leave all other components off (water pump fan ect.) and try again.And yes, if your trigger wires were reversed you would see 10 degrees of timing change but it would be steady.
