Help Avoiding iCloud Duplicates

Hey guys,

I have been trying to figure out how to avoid duplicates on the iCal when syncing to the cloud. I currently have the iPad and iPhone synced up seemingly without any issues - but when I go to add the Calendar on my MBP - every entry shows up as a duplicate on due to the cloud - what steps should be taken to avoid this?

Is the best solution to turn off the cloud - sync up each device to the MacBook and then turn the cloud back on?

Or is there something a little easier than that?

Would love any hints/tips/suggestions.

Thanks,
