I haven't personally used the CA varishocks, but I know those who have. Good stuff. Alston normally doesn't mess with any garbage. I called them a while back about another issue (not shocks) and was blown away at how well they discussed the options, options that I didn't know I had. We went through the cheapest stuff to the more expensive stuff, and it was mentioned how even some of their stuff was really overkill (and overpriced) for my needs. That kind of honesty left a good impression. He could've easily sold me the most expensive stuff he had but chose not to.
