So it doesn't sound like anyone else has done this? 
  
These aren't actually paragliders. They're speed flying wings.   
Feck/G-Spotter- These speed wing systems are much, smaller ranging from 18 to 8 sq meters.  So yes, with harness and wing they weight around 2 kilos.

Ivan-It's not BASE jumping, from the videos I've seen most of them run off.  
  
I'll probably call these guys tomorrow and see what they have. This sounds like too much fun to pass.
