while we are on the subject of shocks;

which manufacturer in your opinions make the smoothest action and most reliable shocks? i've rebuilt my kyosho v1r shocks heaps of times ( at one point buying a new set for the rear) and found the internals of the shock casing had two rings, or grooves arounf the internal sides.

so what shocks are the best? hudy? trinity? serpent? mugen? losi?
