I think the message that comes across is that the rules are kept as simple as possible and will hopefully cover most eventualities with some sensible interpretation.
There could be a million one off situations ...
... I've got a wooden leg ... can I bolt it to the peg during kneelers?
To cover ALL possibilities would need a rule book a foot thick.
I'd just spotted that addition and wanted to clarify the calf/hamstring part. I suppose 'don't take the ****' is a reasonable interpretation of the rules.
Please don't turn the thread into a ... 'well what about this' circus as it will just be the same answer.
PS Oooh the post I was responding too has ... Poooof ... ; )
