After playing around with lights quite a bit when I had the 4x4, I have found that the best Halogen bulbs for my tastes are the Narve +80, aka Osram nightbreaker.
I have used both philips crystal and blue vision, narva arctic white, cheap Austra bulbs and Osram nightstalker (Narva +50). My experiences with the diamond vision:
I do a bit of night highway driving, especially in summer up and back from the mornington penninsular. These lights are brillant around town, they light up signs nice and bright and the light spectrum is great off reflectors, but get on a dark, unlit country road and I found them hopeless. The length in the beam throw was much less than cars with standard blubs. Now, I am not sure if this has to do with the reflector design in the Mk4 Golf headlights as the europeans are brilliant at HID technology, but there holgen-reflector lights used to leave alot to be desired. As soon as I put in the nightbreakers, it was different. While in isolation they give a blue appearance but it is a high intensity yellow light which bar HID, is a longer beam due to the colour spectrum, hence why most fog lights are a very definative yellow beam, it can penetrate the fog layer better.
But, I guess I was too late anyway, but if you're looking at upgrading the high beams (don't know how the polo light is structured, if it's seperate or not), look into the nightbreakers, $80-odd a globe, but worth it over most of the competition.
