What an impressive Resume, you are quite obviously qualified to make comment:
been involved in more blade strikes on 212's/412's than i'd like to (about 6) only 2 of these machines were within damage limits to keep flying all the others reqd major component changes
Most EMS pilots in Oz, [including myself] have never hit anything hard in their entire career, yet alone 6!!
Quite impressive.
