I've been out core mining for the first time in months, and the first time with a carrier orbiting the planet I'm mining the rings of.
The availability of the carrier removes a few things you would otherwise have to cram into your mining ship - like a fuel scoop, possibly FSD booster, heck I made do with a light weight 5D FSD. I also went into the field naked, by which I mean, no shields. But strong hull. The ship in question rarely has shields on it anyway.
The panoramic view of the asteroid field while using PWA is unrivalled, the boost speed a credible 530m/s loaded with limpets or minerals, and the agility around the rocks is unmatched for a fairly compact ship that can haul 96t of minerals back to the carrier. That's enough for me on one trip.
I like the Orca for core mining, but the length does make collecting chunks a bit cumbersome. I'd guess the Clipper's width is an issue, but not tried this ship core mining yet.
The ship'ss last trick is the abrasion blaster and seismic launcher can be mounted centre line to the ship just above the cockpit which makes a noticeable difference to the speed and accuracy of this part of the operation. It helps to compensate for the good but not amazing boost speed for finding the next core to crack.
All round I'm not sure what ship could top it for my tastes, except maybe the Clipper if it turns out to not be too wide. Maybe one of it's larger sister ships. To borrow another writer's phrase, "All hail the Chief".
