3-6 materials. I use 4 limpets when there are 4 materials, and 3 limpets otherwise. I don't see a downside to using the multi-limpet controller vs a class 3 collector which only has 2 limpets.4 Drones when there are at least 3x G5 materials in the HGEs?
And in addition, a Supercruise Assist because no pig needed?
I use supercruise assist for fast arrival at HGEs and stations - you can cut approach time by up to 30 seconds using SA if you know how. I'm happy to lose 4T of limpets for that saving.
