Here's a MARD save and what looks like the same DZ.

Still ended up with a bunch of linetwists but not quite as bad. Personally for me I would want either a MARD or nothing. Since an RSL is the same as pulling your reserve as soon as your risers realease, it will be better in some situations but could be worse if you know your body position will be terrible on release. Since I don't have a MARD, I leave my standard RSL disconnected for wingsuit jumps knowing if I need to I can pull my reserve as soon as I disconnect from my main, but if I have the altitude and I'm in a bad position to deploy immediately, I can take a second to get stable. But that's just my opinion and what suits me. Everyone should educate themselves and make their own choices with what they feel comfortable with. Whats the point of living if you aren't doing what you love?
