I have the RS9000Xs on the Ironman and I have been pretty happy with them. For the money, they work exceptionally well. My next set might be the Bilsteins, only to say that I've tried them.
I've also been looking hard at the Fox 2.0 shocks.

Whetever I choose for the I-man, I'd still like to have the stock units on the wifes VX.
Now I'm dealing with another shirt at Isuzu -someone named "Marie"

Here's the rundown/runaround as of today,
Isuzu: We'll cover the shocks if the dealer says that they need replaced.
Dealer: We'll replace the shocks, if Isuzu says they'll pay for them.

..and now we've come full circle...
