I am curious which ship hull people use the least
mostly the general ones not the PRT specific ones, but those too i suppose

please also say "why" you don't use it

OBRM gives +10 max. population, which gives +10% resources in mid to late game. But that means that any remote miners that can be build are quite poor, in addition to being expensive. Plus that remote mining fleets are very vulnerable to attack.

I haven't seen any non-AR use remote mining.
