I remember you more as Soumya than as cityhunter
In my opinion, go in for the Osram nightbreaker. It gives a definite improvement in light output and focus, will not need any additions/alterations to your bike's electrics and will not put any additional load on it either (as the HID would do). I have been using the same in my ZMA for the past year and a half. Works great.
And yes...congrats on completing 50K on your P200. That IS a milestone...definitely.
Ride long and safe...
