I currently have 2 Hoppers and 3 Joeys. I record on one Hopper, wife records on the other (a lot!). Do not need 4K. My wife wants Netflix, so I need a Hopper w/Sling or a Hopper 3. Do I need two HwS or two H3? Do I keep the Joeys if I get an H3? To be honest, the HDTV my wife watches is about 8 years old. I'm considering replacing it with a Smart TV and leave the Dish equipment alone. Thoughts?
