I've got a Beeshu Ultimate Superstick for the SMS that is kind of stiff that I would like to loosen up a bit. I've got another Beeshu Ultimate stick just like it, but for the 2600, and it has a great feel to it. I'd like to get a better feel with the SMS one. Anyone know the best approach to take when dealing with this particular stick? Is it simply a matter of opening it up and knowing where to spritz a bit of WD-40? Is there some spring I need to replace? I don't want to open it up and start monkeying around with it until I get a plan of attack.
