I'm upgrading (maybe?) from the same Osram Rallye Hyper+65/HIR set up a lot of you have. I like the light output from both. The HIR's are pretty amazing, actually, and I'm not touching those. I am, however, going HID with lows and fogs as I keep losing a bulb here and there and I'm tired of replacing them. HID's should last years. I'll let you know an honest brightness comparison once the HID's are in. I'm not getting them for looks...I want reliable light, and I was perfectly happy with what I had, so I consider myself mostly unbiased.
