Just keep in mind that there’s probably a hard upper limit to how much cargo you can obtain before the chipping from Glaives and/or interceptors requires you to abandon the instance to get what you have out.Phantom is ok for me, but Python would have more space to save souls!
I for one think 32 or 64 cargo is a good middle ground. Though I haven’t tested 32 yet - 16 when I wasn’t yet sure if they’d be corrosive felt a little on the low side for the time taken to get to a Titan(Oya, in my case).
