Engine runs rough - poor quality Bosch ignition wires?

Well, I actually think I have this figured out. Since you don't start a story at the end I'll fill you all in...
Since February my poor little buggy has been sitting. I occasionally warmed it up but never actually drove it due to the rain and any other excuse I came up with. Last month or so I did drive the buggy but started running into a little roughness now and then.
First it seemed that the idle circuits were plugged up and sure enough once I pulled the carbs and took them apart I found many small deposits of crud built up here and there. A thorough cleaning and adjustment seemed to fix the issue but now and then I would hear the exhaust pop and backfire pop during deceleration. I even had some hesitation during harder acceleration. I just assumed it would clear up once I ran enough gas through the carbs as I had added a cleaner to the tank.
This last couple of weeks it got worse and the engine just stopped running smooth. I pulled the plugs and they looked alright. Thinking back on a similar issue I had before with a misfire I went ahead and replaced the ignition wires with a new set I had on the shelf.
Now, knock on wood, the engine is running smooth and I have the power I used to. It seems I have fixed my rough running but I now have little confidence in the Bosch ignition wires. This is the second set I have had to replace since the buggy has been on the road. I have less than 6,000 miles on the engine and I'm on my third set!
Is the quality of the Bosch wires as poor as I've been experiencing or have I just had a run of bad luck? Is this a common issue?
Any way. It's nice out. The sun is shining and I'm driving the buggy.
