Iridium plugs all the way for me, i do notice a difference.
Years ago I had a different set of carbs put on my bike, I can't remember why but I think it was an easier and cheaper option than repairing the old ones.
After the bike was good to go I found that on hard acceleration the bike would stutter and bog down a bit.
Everyone was puzzled as to why this was happening until eventually another mechanic i use occasionally found that #2 carb rubber had folded in on itself on refitting, and was letting a tiny amount of air in. But due to where it is you couldn't see it at all. Thought it might be worth mentioning.

More people are born because of alcohol than will ever die from it.
