I do think there's a difference between 'personal preference' and 'feeling comfortable.' Forgetting about the adjusted address and stuff for a second, I've seen many golfers junk tweaks to the components of the swing simply because they don't feel comfortable with it right away and then state that it was 'personal preference.'

I think you need to give any adjustment a legit chance.

Agreed, 3Jack. And knowing that the Component under consideration is a valid Variation gives one the confidence to pursue it until an informed decision can be made.
