FlowZone 3 Cyclone vs FlowZone 3 Typhoon Question

I need a new backpack sprayer. Anyone own one of these? Obviously judging by price the Typhoon must be manufactured for more of a commercial use. But that can be misleading because pest control guys use these things all the time. Maybe one is better for the yard vs pest control. I have a couple of pump up back sprayers that have served me well, but the cheap straps are not very comfortable. My yard is roughly 8,000 Sq Ft. I’m constantly treating my mom’s, sister, and neighbors yards too. It’s sort of become a side hustle not by intention. My neighbors are elderly so I try to treat them very fairly. The neighbors would rather pay me to control weeds because the local companies charge so much and don’t do a very good job. I spray Celsius, Certainty, bio nutrients like Nutrisolve, liquid fertilizers, pesticides, etc. I want something that is easier on my back and more comfortable with better straps. I don’t care that one cost a little more, I just want the one that’s best for doing these kind of applications in the yard quicker and easier. I’ve done a little Google research, but the reviews are not from people as knowledgeable as the ones that post in here.
