Victor,
You are getting out there, no worries.
As to your original question, I don't think IPC defines copper tooth size anywhere.
When I was still in RF land we called out rolled rather than drum side EP if we needed real smooth.
And as you have stated the peel strength drops dramatically.
Good Luck,
FNK
