From another link you had posted a while ago, it was mentioned that the H1 bulb combo for dedicated low and high was a better choice than the more common H4, since a low beam using an H4 only uses part of the reflector for low beam, the H1 uses the entire reflector.
yes sir, that's my take as well.......any lamp that has to pull double duty can't be as good as a dedicated light assembly.
i do remember Daniel Stern recommending a 7" lens to me for one of the bikes.....that one uses an H13 bulb, which has no low filament shield an is said to use the entire reflector as opposed to an H4......unfortunately it's one of those "clear-lensed" varieties where the reflector does all the work. i just find them butt-fugly and don't want another one, i'm taking the clears i have off my bike for that reason.......
i'm have photofucket problems.....but i have some pictures of the CSR low beam too. it's for LHT and can't be used here, but GLORIOUS it is.....Jackson had one dusty set at his shop and sent a surprise-box to my house. i believe he has more high beams. he sent these to me i think because he knows i'm insane....and won't sell em. though i told him he should have. men like him are rare....and i'm fortunate to have have "met" him.
the Hella bi-focal H1 low beam is a good match for the Cibie high.....i've seen the photo-metrics for those v. the CSR low and it does come close to it's performance......some threads on the subject are on the net and it seems to be the "only" choice for the best quad setup, especially since they're still available.
my quest for RHT lows will never end until i get a set, but i drawer a line and won't pay $645 to that guy on ebay for them......as much as i consider it.
right now i have to concentrate on getting the buckets for the SC lenses....and getting rid of the LHT H4's i got......i have a note sent off to Demon Tweeks to try and secure other Oscar housings and possible swap off to the proper RHT H4 lenses. i'm sure a reply will come soon to answer my query.
