Right now I'm sorting the same problem following unscheduled off road excursion
Looks wise I much prefer the round headlight, one decent reflector is better than two small ones. Also, thanks to one or two peeps on here and elsewhere, I've figured out that the old school glass lensed headlights (ie the ones where the lines on glass focus the beam) have one big advantage over cheap, clear lensed like for like replacements. They don't melt, meaning you can up the output of the H4. A friend had a an 07 gix 750 fighter and used an old headlight as described which takes more powerful H4s happily, and focusses the beam nicely so he has plenty of light without blinding oncoming vehicles.
