I didn't following the Nick Lappos reasoning. My way of thinking, if you need to baby the helicopter because the tail rotor margin is what it is, well, baby it. And if you don't baby it and you get stung because of it, well, to me, blame that on the pilot. Don't blame it on the design, and don't solve the problem by using a helicopter with better design (unless of course it's practicable to do that). You just have to use the tools you are given, in such a way as to remain within the safety margin. Using as much baby as you need to.
