2 collectors will not keep up with 2xD2 lasers
250mj shields thin for interdictions and HAZRES
200 boost speed too slow to evade pirate NPC's
First, assuming you wish to mine efficiently, you won't be able to get through the shields of the initial attack in the HAZRES with 2x class 1 beam lasers. Second, if you survive, possibly by staying cool, it would take forever to collect. Drop mining lasers to class 1, it was overkill, you then need 3 collectors but you might get away with 2 if you are close enough to the asteroid. Third, once full of painite, the inevitable interdiction will be hard to escape without escort.
Use silent running / reboot shields (once update 2.3 is available shields come back at 50%)
Engineer ship to stay cool and reduce signature
Fix collector vs laser ratio
Engineered ammo capacity for heat sink and chaff
Hire escorts, pay in painite and trade dividends
The above is not a recommendation, rather tips if he really wants to use a T9 for mining. Good luck and report back, some us might be eager to hear your story if you try this.
