Like most things you'll find outstanding people achieving great things going against the agreed norm, so really there are no rules for most things we can chose to do as a hobby
However established "best" ways of doing things do seem to have been time tested and seem best for the average person to do things as well and a safely as possible , so is always advised to follow the "rules"
This goes for bass player, skiing , Diy, racing or anything in life
what a silly post for a Monday morning , sorry
