Spin wing & Aser
Spin - You are absolutely right in the same way that the difference between a medal and a court-martial is sometimes nothing at all, it is the outcome that is important. Notice that in my example I was talking about a 'headstone'. This rather implies that it didn't work out. My message was meant to convey the caution required when treating the absence of prohibition as tacit permission. If in doubt - check.
Aser - Yes I believe that in an earlier post I mentioned that 102 should be used for Cat A, sling ops and hoisting.
