OK mate, I'll bear that in mind.... I asked them on Saturday at ADI. No firm answer, just a load of wibble about testing.... Yarp, that's K03-tacular. The IE site says they flow 550 at 43.5 PSI, which is 3 BAR, so fingers crossed. Cheers mate, I'm interested to see what will come of it after all this money I've thrown at it.... lol.
