Hi,
dual audio is good for dslr camera.
But as an option for more intermediate videographer, it would be interesting to create a XLR block for dslr, just like this one for sony camcorder:http://www.bhphotovideo.com/c/product/892383-REG/Sony_xlr_k1m_XLR_Adapter_Microphone_Kit.html
I tested this xlr block and it makes good results for external mics.
it will be another option than dual system for a more intermediate videographer
