Ivan, I understand your point of view on this, but the other side of that suggested blanket ruling would then be penalising those who have put a good deal of practice into kneelers and as such may not be seen as fair on everyone else, as well as taking away an element of freedom in course setting.
Playing devil's advocate would be that you are aware of the requirements for FT positions and choose to take part despite knowing that you are unable to use one or more of those positions, so therefore suggest that the rules that everyone else shoots by should be change as a result of you not being able to shoot a certain position.
I have asked previously, but just how many people actually need to use the adapted positions?
FT by its very nature is a physical sport. Is it always right to adapt the rules used by a large majority to suit a minority? I don't know the answer to that one.
