Re: Howdy from a Chicago Aikikai student.
I see where you are coming from Terry (testing raises the ego) but there is always a flipside to this. IMHO, testing MAY lead to this depending on the intention of the person when they began aikido. It is your perogative not to test and that is your choice.
But also remember that you honor your teacher and your sempai (not to mention your dojo) who "bring you up the ranks" as you continue your practice. Test if your sensei tells you, don't test if your ego tells you to.
