Heliamphora on the Tabletop Mountains

[triphyophyllum]

I am traveling to Venezuela, and climbing one (or possibly multiple) tabletop mountain(s). I have always wanted to see any specie of Heliamphora in its natural habitat, so I would like to know which mountain has the most Heliamphora. I am planning on taking some photographs for a book I am writing (It may never be published.)

Mount Roraima is the usual "go to" location to view these species, but I'm not too sure if it has a higher density or diversity than any of the other surrounding tepuis. I know its the tallest, so there is likely a higher density of colder growing species.
