Can anyone give me a good reason "not" to install this on my '04 GTX 4TEC SC LTD. I like what I have read about the Block-off Kit and am seriously considering it. I know there are plus and minuses to everthing but am swaying more towards installing the Block-off Kit.

We don't recommend it for recreational riding and/or if you let inexperienced people operate your craft.

You will be better off going with our Competition O.P.A.S. Block-off Kit. This keeps the fins up all the time so they will be somewhat effective in the event a situation arises where steering assistance is required.

I recommend it for rec riding
It will make your ski feel 200 pounds lighter and alot more playful.

Does the 04 GTX SC Limited have OPAS that raise and lower? I thought that was just pre-2004 skis.

yes Mike, the 04 raises and lowers.

The `03 & `04 GTX as well as `05 RXT have the OPAS that raise and lower.

Thanks GH, I sort of figured you'd give that response.. I could not remember where you posted something a few days back about recommending the removal of the O.P.A.S. Hmmm, what did everyone do prior to O.P.A.S??

Riva also made a good point about rec riding too. Guess I will ride another month before I decide. I guess the good thing about adding the Riva Block-off Kit if I go that route is that it won't be much of a dollar loss if I go back to O.P.A.S. Thanks for the honesty Riva and not just trying to make a sale....

OPAS has got to go. I love the RXP without it. Loosens it up a bit. Needs it.

I have an 06 GTX Limited. I am currently putting on all RIVA.

- Pump Wedge
- Intake Grate
- Sponsons

I really don't know what to do with regard to the OPAS.
Should I just Block them up (Competition KIT),
or totally remove and Block off? Exactly how unstable will the ride be if I only
block them up, given the other handling mods I mentioned?


Thanks in advance
