I do, yep, only recently discovered it but it appeals to me in a very childish way :P

I shall enter:

Drive (on ZED) and Kick Robut (RW series 2) for the superheavies
The Hurting and Quaestor III for the heavies
Doom (RW Extreme 1) and Hard Cheese (same) for the middles
and Isolation (stats up shortly on ZED) and Satanix (see Roaming Robots site or http://thedavidleague.tripod.com/teamhell/http://thedavidleague.tripod.com/teamhell/ for details) for the feathers.

Hope those are alright.
