I was messing with my jato the other day and noticed that the suspension (the front moreso than the rear) seems to sag. What I mean is I can push down and the springs compress, but they don't rebound/spring back. My first guess is that I just killed the springs when I had the preload as low as possible for the longest time and because I haven't broken any shocks nor had any oil leak from any.

So basically my question is, what spring and shock oil combos does everyone run? I'm going to the LHS tomorrow and thought if anyone had any suggestions that seem better than the stock springs and 30wt oil I might try those instead.

Thanks
