Thank you, that was helpful.
[updates 'to do' list]
What is your planned play for the next month or so?
FSD Booster can add up to 10.5Ly on range for no extra fuel cost, nice for going further, quicker

(or putting back some range that big guns / reinforcement have added)
The Guardian SLF's are both nice to look at and can attack Thargoid ships - not tried them against 'normal ships' so...
Going out and doing the 111 million Ram Tah mission will use a few days of play time as over several systems and a lot of SRV'ing, but will also net you a goodly sum in exploration data (and might push you close to/actually Elite exploration.
Doing the Module/weapons/ships is less time consuming, but will require a bit more pillar scanning to get data. (distance is 700'ish Ly from bubble)
Best 'beginner' type ship would be a DBX with an engineered FSD and mainly lightweight modules. PD on top of ship recommended.
If you just want to get your own back on Krash, you won't need most of the Guardian stuff... Just leave us your Last Will & Testament for safekeeping if you choose that option...
