IMO we have to rule out any direct route between Port de V and PortdelaG. There's no trail and it's impassable. I think the "shortcut" is too difficult and doesn't really go to the PortdelaG which seems to have been the goal. Plus, LE says there's no evidence ED was at the RdeV. Here you go for Cabane de Besurtas to PortdelaG to PicdelaG. There is no trail on the map for the last leg, but this blog indicates (as I understand it) it's obvious at the Port. Montesymasdebucuesa: 42-14. PICO DE LA GLERA POR LA ARISTA SUDOESTE. 6-6-14.
