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...
I agree with Matt the new EPO2 blades are the best. I did not realize the white stock blades are EPO2 as well. Are the blades on my 'Ventura' boat EPO2's?
