Hmm. Just a short question. I believe the 435 was a short shotgun? The corresponding cardioid was the 406 while the 405 was hypercardioid?
I have a pair of the 406P48. Very quiet and nicely sounding mics. With a sloping bass cutoff starting at about 80Hz which should make them perfect for concert taping. Alas, I do mostly classical music so these do a lot of work as spot mics.
My belief, not really tested, is that using a shotgun a spot, even if short, can be a bit problematic. The reason being that the shotguns have a lot of lobes of sensitivity off-axis and these lobes do not sound very good. As a spot you would probably get a lot of other instruments as well.
