One minute is was at the beginning of the runway, next it was along side me, not fast enough on reeling in the Tamron 150-600 and clipped its wing

Something that I picked up some years ago, watching a youngster with a Sigma 150-500mm, was to treat lenses of this type as old "one-touch" zooms; rather than using the zoom ring you push/pull the front part of the lens. I'm sure that there a many reasons why you shouldn't do it this way and potential damage that could be done but it is a lot more convenient and quicker.
The first trip that I did with my original (non OS) Sigma 50-500mm I missed a number of shots whilst trying to wind the zoom in or out and as I as still shooting film it was more of a pain to crop. Likewise I also missed more shots by grabbing the wrong ring when trying to zoom and altering the focus.
Having changed to the later stabilised version, after I went digital, I have adopted the above method; it forces you to grip the lens further forward than you might, helping combat shake and keeps your hands away from the focus ring:cocksure:.
