Picked up a set of Park Tool cone wrenches at the LBS, and just to say I have them I got a set of the old school Campagnolo cone wrenches off of eBay also. I like having two of each, feels like I have better fine tuning of the bearing pre-load if I am adding or subtracting torque from both sides, and I can keep things centered too.

Complicated, yes, I'm an engineer, its genetic they say.
