You have to use HPA on a luxe.
Any marker that is an ElectroPneumatic (electronic and has a solenoid) MUST run on HPA and nothing else or you will destroy the marker.
Low pressure will let the luxe be its most consistent.
Angels can use a high output tank if you do the minireg mod or let it use any normal inline reg on the market.
G6rs have to use Low Pressure or ELOP/SLP tanks or you risk blowing lots of seals.
I would say the same for victories, but they can withstand higher pressure tanks, albeit they run best on Low Pressure or SLP/ELOP as well.
Just about every marker made after 2005 will be able to run on LP and most likely be better suited when running off an LP output tank. (This excludes mechanicals and most low-ends.)
