I had a long post about the complex ethics involved in this roping situation, but then thought "to hell with it".
The only HO I find to be really debatable is on an initial H2H pass in a 1-on-1 situation. Beyond that, all's fair. And even in that situation, it still depends. Once in a while, you've just got to take the wing off that Lala. Why? "Because **** that guy for flying a Lala", that's why.

It's a public service.
And if you get killed going H2H with a Mossie or 110 under ANY circumstances, you had it coming.
