Panther Clipper has always been documented at around 1000t (max) capacity; where did you get 1500 from? Also Frontier capitulated on type-9, because people kept demanding. It's fine that they've increased capacity, but type-9 was never intended to be the top trade ship.
Personally, I'm not especially fussed what ship is the best at what.
I'm more interested in retaining a situation where every ship requires that a player has to make choices and compromises.
That being the case, I'm more disappointed about the armour buff the T9 got a while back.
Especially now, with the T9 getting more cargo, it would have been nice if players were forced to choose between an expensive, tough Cutter or a cheaper, spindly, T9.
If it was up to me, I'd probably knock 100t off the weight of the T9 and then cut it's integrity in half. [where is it]
