5/5, Really effective and ridiculously good fun XD I've stripped half a ton of armour (as low as I dare!) for 3 more shots, and would put in a 225 or 235 engine if I had any spare, for more ammo - but as is, it's a great speed for such a heavy hitter. Range quirk is great for it too!
I'd run xl225, 35 shells, 2 mlas. Long term it has much higher damage potential. Doesn't really matter any which way it'll hit hard.
