Once your assessment is done..Buy the system that Best Fits your needs..I refer again..BEST FITS YOUR NEEDS. I, like Chief France, live in New York, where we are being required to have a Bailout Configuration. I also teach FF Self Rescue for the State of NY ;OFPC.
Good Luck with your Inquiry, but please do as Chief France says FIRST, and then Buy the System that BEST FITS YOUR NEEDS. Here in NY, a requirement for purchasing, is that all the Components must meet NFPA 1983, so use this a a good pre requisite for your purchases.
