I'd say the original EPO's are still good. Unless you have the cash, the desire for new and maybe the old are trashed... keep the old. They will be fine. I do agree though that the new EPO2s are the best yet.

On the delamination (bubble) issue... We have not had claims since the first (known issue) batch about 2 years ago.

The white stock blades are also EPO2 blades...
