Hi I have been using Maxell CD-R Pro 48X700MB, 80 min and triple coated.
I have found these excellent as the coating indeed seems to keep them from getting scratched more easily.
I purchased them at Staples on sale, $9.99 for a 10 pack. Unfortunately they don't seem to package them in high volumes.
They certainly do the job for me.
Just my personal experience, I also use the Sony Brand but there is no specific model name as you had mentioned.
