Re SARCO's post I think the 92 has faired so badly against the 225 in ABZ because there is only 1 92 but 6 225's, if a 225 goes down simply roll out another, no one knows, the others take the slack, the 92 goes u/s everyone knows as it can't be replaced and it's noticed to be abscent. As HC rightly says it's a spares problem that's the bain of the 92.h
