Has any one use Procircuit nation spring tubes and has anyone usd Factory Connections national spring seat? How about the RG3 smart valving vs Racetech gold. I am over 30 intermediate rider. My suspension is set up pretty sweet just looking for a tad bit more plushness. Any suggestions. I'm not gonna send them out to PC or FC I can pretty much do it at home for less than 700.00. Just curious as to these few bolt in items. Have any of you used them. Also my shim stacks are set good as well so. Spring rates are correct. Just curious of this stuff is actually woth the money and which is best. Please experienced riders and people who know how this stuff reacts. Not bashing but a lot of people send their stuff off and ask for the best and do not understand how it actually functions. I have had both FC and PC suspension re valving but never the tubes or seats. Thanks for reading my postal be this will help other save some cash as well.
