Gotta say that if youre not happy signing something, then DONT sign for it.
I've been A&C for 25 years with limited Avionic Extensions on my types. Over the past few years, with the introduction of more computer based systems (777, A320), we have had to adapt. It only seems natural that we take that last small step to achieve B1. You know what is required of you, and you know your own personal limitations. The choice is ours to make. Not an easy choice for some.
