Hassan,

No problem.  I didn’t feel slighted.  It takes me a few days to get back to some posts myself.

RE: changing one’s arms as one’s tastes change over time—

Dependi of course on the design of the arms themselves, but there may well be great latiture in just depicting the same arms in different artistic styles & with greater or lesser artistic license.  Mine have gone through at least three changes in style with no change at all in the basic design or blazon, & I doubt that I’m in any way unique!  (My arms are, but I’m not…)
