Well so far this system is a bit of a mix.
The Metallic ring is good.
The Metal rich was a waste of time, Tried a double first, in the double area and one of the hotspot centre's, then one of the triples, in the overlap and the middle centre - got a few Cores, unfortunately a fair number of them were Platinum or Painite, lasering rocks was a waste of time very little of any value, maybe a Cores specialist would do better.
Just started my first run in the Icy ring, planet 8 B ring, it's looking good, plenty of rocks with for a Icy ring a good return, better than one for one with limpet use.
Must admit that metal ring was fun, Close the scoop and hit boost, 275 top end with a fair bit of drift and no brakes

Weapons focused PD and pips in the wrong place don't help either, almost scratched my hull
