Best HID set up to go with?

[PARAGON]

I have the Xenarc HIDs in my H2 but have had HID retrofits in my Denali. The Denali has a standard projector setup of for the low beam and I put the retro HID bulbs in place of the stock bulbs.

Biggest difference from an observational standpoint is that the projector setup has no hot spots. The light is smooth and even where the Xenarc HIDs have bright and dim spots in comparison.
