End of financial year bonus has got me thinking about what I should do with the spare cash....apart from paying endless bills

Ok so I'm thinking suspension. I'm currently running Konis/Kings but I'm thinking of going one better. If you were to have a choice of Jap spec Tein SS (GSM40-B1SS3) or Aussie spec Tein SS (QSM40-EZSS3) at same price, which would you prefer? and why?
From what I know Aussie spec Tein SS are developed for the Aussie road condition, valving, damping factor etc was change to suit, development was done by Fulcrum (Tein's Australian Distributor). Where as Jap spec Teins designed for baby skin Jap roads.
Cheers
