BR9ECM (and R5300A-95)
Personally, I've never seen anything to justify the cost of iridium plugs. BR9ECM work perfectly and last forever, so long as you don't flood them. Even so, I can categorically say, in 25 years, I've never had [or seen] one fail. I'm sure they have, for someone somewhere, but it's certainly not something forums are filled with, and I believe it's pretty much the standard plug for all the 90s 2-stroke race reps.
Edit: As above, all 90s NSR/RGV/RS/TZR
