Plug Fouling Query

[dryvern]

Sunday I thought I had thrown/cracked a rotor tip (ouch), but things look as though it is electrical i.e. flooded plugs (I find out tomorrow, fingers crossed).
I already have my Magnecores to go on, but my question is this:

Is there less chance of a racing set of plugs fouling than standard?

I only put a new set of nines on, around 6 weeks ago before a tune at WGT. Currently around 310bhp but going hopefully to 400bhp on twins with mods in hand.

Trying to decide on best plug option.
