Good idea - am sure many of us (me included) have the original Spax etc left over after an ATR / Ohlins upgrade, for a low cost fix!
I do have an original pair of Spax as well but I am sure that Biggle wouldn't want them after using the Suplex shocks. The one good Suplex I have will mean that he has a pair of working Suplex again. Not sure how long they will last though as it appears they do have a tendency to leak and there seems to be no easy way of servicing them without some drastic mods.
