I've also been done for a DR10 mate and its a killer for nearlly everything in life. Every employer sees you as a walking piss can who sits in the park swigging cider, harsh but true. I got told by CTC that it failed me and i thought honesty might shine through. If i were you id leave it till 5yrs and tell no-one. Basically ignore what you've been taught by your parents and teachers all your life about being honest and take the advice of a complete stranger and lie
