I tried to see how strong I could make the Mandalay if I just went all-out with the goal of making it as much of a tank as possible, capable of soaking up enormous amounts of damage. I got these stats out of it. I'm not really a combat ship expert, so I don't know if these are good or mediocre:

Problem is, if you get into builds like that, you have to ask yourself why you're not building an FdL or a Python 2 instead.
A P2, in particular, can have (almost) twice the shield and hull, more firepower and a similar jump-range.
I'd also wonder about power and weapons with a Mandy' combat build.
4x C2 and 2x C1 hardpoints are okay but they're not great... and, after you've loaded the ship up with SBs, GSBs and other fighty parts, how much power is left for weapons?
