I have Indys and I put the Blue medium/hard indy bushings (standard conical) in and change them maybe once every year or 2. I use all the washers stock. I think the Blue bushings are good if you are a bit heavier like around 200lbs, then you can tighten a little bit more and they dont squash out, like orange ones do(also depends on stage) but you can still turn great and have loose trucks for you, if a skinny guy gets on your board they will think your trucks are tight, but i keep the nut just over flush, i have 149, 159 and 169s all blue bushings. front truck is a touch looser and never switch those around.
