if you know where the jumpers are travelling to and from and you are on the location, why not just ignore the bs and gib the transport really fast (as in several bombers or a cruiser, they'll have a hard time botfeeding the transport when met with that kind of firepower - I noticed a lot of jumpers use kujiras or whales, both of which have weak hull) and loot its contents with a transport of your own? The mkiv jd takes 1000 seconds to charge, some drop fuel in space that you can tractor or destroy, and as you say jumpers arrive ~20k from their destination, meaning you got time both at departure and arrival. Problem is knowing where they are at/going to and be there at the right time, if you've got that nailed down I don't see what's so difficult.
