According to page 337 of the core book: Micro rope can support a weight of up to 2,000 kg; all other ropes can support a weight of up to 4,000 kg. So I don't think weight should be an issue. I think I'll go with lowering him down as long as it's not going to make a bunch of noise like hauling him up, shouldn't be long as I don't drop him

.
I'll get an IP up shortly.
*Edit* Only now do I remember that Knives specifically bought a grapple gun for this very reason. I'm dumb. Plus I assume it's a little big to just tuck in your knapsack, so that's why I figured it would have left it in the trunk.
