this is an interesting point.
Just took a DBX to crab, station x. reinforced Shields, SRV, 3 weaps (2 LW MC, 1 eff burst) 3 shield boosters (all class E), 1 x heat sink, D rated thrusters, D rated LS, Sensors etc. A rate PP, D rated PD. Also ADS and DSS. Jump range 52LY, maxed is 54.5LY. FSD long range eng'd grade 5.
Always wanted to go to the crab, been 3 years till i got round to it, did it 163 jumps. Got CR16M for scans.
Does it need to be uber-light?
Edit - nearly did it in a courier, seriously. It does 30LY jumps fully kitted, admittedly LW bias for the grade 3 enhanced thrusters, but toyed with the idea.
