Also, and I get that this might rub you the wrong way, but since you're selling a rig with a Katana 107, and in that same classified ad are looking for a 170-190 main, I would STRONGLY recommend you do all of your gear buying through a single rep who knows exactly how many jumps you have. A 150 is a high performance parachute regardless of wingloading. I'm making a lot of assumptions about you, but a traumatic brain injury will change your whole life forever. Every single person in the sport for more than a few years has seen it happen. Gung ho people downsizing too quickly and ending up with broken bones and TBIs. Sorry if my assumptions are wrong, or if that came off like a dick thing to say. It's just kind of rude to bounce in front of people if it's something you could have avoided doing. I know I don't like to hear people screaming because their bones aren't in the right order anymore.
