What version of BWA builder should I use?

Hi there,
I was wondering what version would be the most appropiate to backup SecuROM because in some post I read that since version 4.2.8 or so Blindwrite started with emulation based copies so, should I use the new BWA builder 5 or an earlier version of it?

Another thing, is there something I can do to select te extraction speed if my readers don’t support manual speed selection?

Hope someone could answer these little questions :bow: .
