My boy has improved enough on his GPX/Unison 90 at the track to warrant a new rear shock. Have looked at the Works shock and have seen a few in our area installed on 90 size quads. Wondering what your opinions, experiences are between Works and Elka? I'm not looking at the fully adjustable remote resevoir model (a little pricey at this time, but may wish I'd gone this route in the end). Not trying to open a can of worms just trying to verify a few comments I've heard about the way each company sets up there shocks. Thanks for your time and comments.
