I guess I will throw my .02 in. I bought the MKV at Dayton last year. (Not one problem with the rig I might add). It has 2-1.8s and 2-250s in addition to the 500 in the sub and the 400. You can't beat that combo. In S&P it's like slicing tissue for samples for a microscope slide. Doubling the bands may be a conservative estimate in my opinion. Good luck with your choice. Mike/AJ9C
