I prefer the better quality plugs, like Platinum or Irridium as they will fire a spark across a given gap at a given compression pressure, at a lower voltage that standard plugs. These aren't exactly cheap, but the good stuff never is. On the upside, they might just outlast your engine.
Platinum plugs actually DON'T run as well as normal plugs. People just think they do because they cost so much. The reason they are used is because they last consderably longer (like 100,000+ kms). Mostly you won't notice the difference. I run Iridium's on my Subaru without a problem, but when I tried them on my 13B turbo the spark broke down at around 6500 rpm.
I've also read dyno tests that consistently show a drop in hp with platinums (stuff all, but still a drop).
Anyway, good to hear you're enjoying the Webers

Is that 100hp at the wheels? Cause thats pretty good!!

My A15 with twin 40's made around the 65hp mark I think from memory
