Any Advantage in Parking domains at high PR ranking Sites?

[SmackDog]

Just wondering this as i have several good domains that are just sitting at Godaddy at the moment.

Is there an advantage in parking these domains under my current PR3 ranking sites?

I was told i could just have the domains redirect to the current site until I am ready to develope them. Is this a good idea? Does it matter?

Why not get a unique page up for each of them and let them sit and age. I am always afraid of parked pages. Mainly because and I could be paranoid but you have all those outgoing links to basically everything under the sun on your site.Godaddy told me I dont need to be concerned about that, but I do.
