So is it worth doing all these changes or just waiting on the .4?

Lately, it's been tough trying to keep up with all the changes (hrc hubs, springs, etc.) And I'm running 4 teknos. I guess it's probably only been about $120 + shipping, lol, total, but it's still extra loot. If the .4 is going to be released soon, I'm wondering if it's worth it. I guess some of that too depends on how many more changes are coming. It would be nice to know so I could decide what to do. I might change one of the buggies and see if I like the feel.
