Love Wade as he's a local now and a great guy. But, the greatest ledge skater of all-time is Henry, and I'm not sure there is much of an argument against that (outside of how you can debate anything in skateboarding). Pack of Lies invented so many ledge tricks its beyond ridiculous to think about 30 years later.
edit: Of current skaters my favorites by far are Lucas and CK1. Shane and Carlos are unreal.
