I'm getting my MBP 15" 1.83 back from the Apple repair depot on Monday. The hard drive and top case were replaced. Considering that I will have a new hard drive with a clean OS install I have a question: should I use the backup image I made via Carbon Copy Cloner to reinstall my apps, setting, docs, etc. or would it be best to perform a complete clean install all apps individually? Is there a difference in how I can expect the OS to perform with respect to speed or efficiency using either method?
