Jet canning still has its uses - for example - Run SM for 9 hours and you will yield around 4 mil m3 of veldspar (give or take)
Mine to a can and use an alt to haul in the same system with the same bookmarks (fleeted) you will get the same volume in under 6 hours. Obviously fleet bonus plays a small part (extra 120m3 per laser per cycle for me) but its the non stop mining and minimal travel the Hulk makes that wins.
Also while your waiting for enough to haul you can equip your Itty (or hauler of choice) to salvage wrecks - just dont forget a tractor beam. Or if your really clever fit scanners so you can time the lasers to perfection for that extra boost (would probably take it down to 4mil m3 in 4.5 hours).
Of course it's a hell of a lot easier to let SM do the work so your not bug eyed the next day from mining for 6 hours staright
