I, Personally do not use a harness
But many of our senior members do. I'm talking people 65 and over.
I would say there is a high percentage of people shooting FT in the USA over 65 and shooting FT. It's not a young mans sport here.
What is the age demographics of FT in the UK? I ask this as I've not been to a match there (yet). One day I'd like to fly over with my EV2.
I am a youngster by comparison (50), live in the USA, and don't wear straps.
