audio help/advice please for my t3i
 

hi all,

i have a t3i and i want to record good audio for wedding speeches and other events.
i know that most people use wireless mics with a zoom h4n.

i just received a shure ulxp4 receiver Shure Americas | ULXP4 Professional Diversity Receiver
and a shure uc1-kk transmitter and shure lav 183 mic

question - should i stick with what i have or sell it to buy 'SennheiserEW112P G3 Bodypack Lavalier Omni' which is smaller and suits my needs better?

thanks in advance for any pointers. i dont know much when it comes to audio, hench the stupid question.
