JetMouse,
I've just taken the "Morrisby" and "CPI" psychometric tests with Pilot Assist (www.pilotassist.com)- I am awaiting the results - they were administered by a recruitment officer from one of the UKs main airlines and I am sure that if you get in contact with Pilot Assist they will be able to let you know more! In the meantime - keep your fingers crossed for me!
Cheers
