So you are telling me you do neutron boosts to break the monotony? Great, then you clearly don't need more jump range as you care more about the quality of your voyage rather than its speed.
In case you need to go to a fringe system, the DBX has got you covered with its max jump range of around 65 LY with the slight buff to FSDs with the new engineers.
I outfit for jump range because I need it to reach fringe systems, which is where I do the majority of my exploring. It's my #1 priority when designing an exploration ship.
With that in mind, both my DBX and Asp X are engineered to the hilt for low mass and high jump range, and both carry the six modules I won't fly without: ADS, DSS, SRV, scoop, shield, and AFMU. My DBX jumps 62.3ly fueled up, I can't get that number any higher with the modules I'm carrying. My Asp jumps a bit less at 57.9ly. While the DBX has range the Asp scoops faster and has a slightly better view, yet I've been flying my DBX ever since 2.3 and I've loved the ship despite it's terribly slow fuel scooping. There is a trade off between the two ships which allow for a good choice depending on priorities, and it's worked great since 2.3.
Now factor in the Guardian FSD booster. My DBX has no free slots, it can't carry one, yet my Asp can easily fit in the 5H booster and gain that extra +10lys of range. SO, after 3.1, my Asp will jump more than 5lys further than my DBX,
AND it will scoop fuel literally twice as fast. The wonderful tradeoff between the two ships which 2.3 put into place is about to be annihilated by update 3.1, and from my perspective the DBX is about to become a pointless ship once again.
And yes, this makes me sad, because had Frontier simply made these fracking boosters utility modules then
ALL ships could equally enjoy them. Now, only certain ships with the space to fit them in will be able to. From a game design point of view this just seems utterly silly to me, dividing the fleet of ship choices up arbitrarily like that. It's only serving to make some ships a lot less appealing in general than ships with more internal space, and IMHO Elite needs more diversity in ship choices, not less, especially when it comes to jump ranges.
