    One sets the pump back 2" and the other is a pump that bolts right on to the pump shoe.

    The pump extension will improve hookup and top speed.
    The Skat pump will improve hookup and reduce top speed.

    How much top speed reduction?

    From the 2 stroke times it seems that the skat setbacks were normally good for some extra hookup and speed....

    I haven't heard anything about Riva's kit lately. I thought it would be a break through mod.

    I run the Riva and the hookup is a different ski on RXP with setback. It totally changed the ride and now can hold its own in the rough if you dare.
    I could see how in the twisties it might not be that good, as it does change the way it turns. Performs awesome running all out!!!!

    I see your T-x top speed is 75.8, would you let me know what your mods are?
