The LZOS ones are not Fluorite as such, but as you should know, the measure of a good lens is not in the glass, but in the precision figuring and propper mating of the lenses... The TEC 200 is an FPL51 doublet, yet colour correction beats 90% of FPL53 triplets on the market thanks to Yuri's superb lens design...
Just perusing the APM site, because you got me thinking of dream machines...  The 10" F/9 is actually quite affordable at $34,900 USD. Your choice of straight through or folded setup (Folded would be the way to go for portability reasons...) Weight wise, a PME should carry it no worries... especially a folded version, would only be 20" long..

RIGHT! SOLD I'll have two!
a 12" F9 folded APO for visual and a 12" F5 astrograph 4 element Petzval.
