IIRC, Eric Embry and Koko Ware both broke their wrists taking the scaffold bump, Embry's being from the ridiculously high WCCW scaffold.
The famous scaffold matches almost all had smaller guys taking the bump (Ware, Mantell, Jarrett, Greene, Dundee, Eaton, Condrey, Lane, Cornette, Rich, Embry; only "bigger' guy I can think of is Idol and it's not like he was Warlord or Barbarian's size) so it was definitely new territory for them to take the bump.
