Hydrogen's density sucks, and makes the LOX-LH2 reaction suffers because of it. These are alternatives using Deuterium for higher density. If someone can make Deuterium fluoride the D-F reaction should be superior to its H-F couterpart..
For those wondering, The LOX-LHD reaction is slightly superior to the LOX-LD2 reaction.
