I had that noise with my WP-40 and it went awsy after about a month.
I don't know too many people that have the twin linkage controller yet so there is not much feedback on them. Assuming there are no problems with them I would go with the twin linkage.
The twin or dual controller will definately give better sync then 2 single controllers.
Is this the noise you guys are hearing on new WP60s?
They've been in the water a few days and it's driving me nuts...
Should this go away after a slime coat builds up?
