I just ordered a set from amain since my track is lagging and i ordered a set of the 1.6's from rcplanet.
Are you running them front and rear? and with what springs?
I put togeather another pair of shocks and had some avid 2+2 pistons (1.6x1.1) and ran 32/30 oil with the pink/gold x gear springs and it felt pretty good on our fresh layout but i think it might be better with the green/white ae springs.
I have them front and rear, Avid springs yellow front red back.
