In fact, I believe AB fixed thrust lever make things much safer, because you actually follow the N1 gauge more closely, (actual thrust) rather than selected thrust from TL position.
Just what you want. On a wild and wooly day, power going up and down like a whore's drawers, you're working overtime just to fly the thing, now you think it's it a great idea that you have to look at the N1s all the time to see what's going on with the thrust? No thanks. Give me moving throttles any day.
