In the market for a new wireless system and looking at the Shure. This is for speaking, weddings, awards ceremonies, etc. Not singing (maybe at a wedding ceremony but hasn't happened yet). Should I go for the SM58 or up to the Beta 58 with it's hypercardoid pattern? I'm trying to eliminate feedback, especially during toasts at weddings. Some of the layouts don't allow us to set up ideally for mic work.
