Thanks again guys - the airport I'm training at has two loooonnng tarmac runways at approx 90 degress to each other. Large commercial traffic only ever seems to use 17/35 and we vary between that and the secondary r/way depending on weather. No chance that I would even ask to interfere with 17/35 but perhaps on the secondary I might request to have APAPI switched off - if tower seems friendly I might even ask them to inform me when I'm a few feet off the ground so I can judge my landings better, coz I'm damned if I know
