I also bought a bunch of Larry Heuers from Bob at the Paph forum and mine have bloomed out very nice. When I was SouthEast Asia last year I was fortunate to see both LH and Shun Fa Golden side by side and the difference I noticed was lack of purple tesselation on the bottom side of the leaves on the SFGs. My LHs from Antec have the purple markings. It could have been a trait just from that grex but food for thought.
