Do you think I could get away with the fan out without using blind
vias?

If it saves me time - of course! My reply e-mail address is valid /
working.

As I can see now, only blind vias would be missing but provided I will
not end up being traped in a dead end with eagly, I'm fine with
upgrading. If they only could implement some kind of online upgrade
option. Sending in the license certificate and then waiting for the
upgrade to arrive by snail mail is really not so cool.

Thanks for your reply. This helps a lot.
