BD-19 402 3 B-ring (about 38 lights from the CG system, common reserves) has 2 Monazite hotpots that have proven very well for me so far, rarely more than a few hours for a full load of 224T, a little longer if you want only Monazite and do only core cracking, but the rocks also feature Uraninite, Samarium, and other CG needs if you don't mind doing subsurface and laser mining as well as deep-core blasting. The two hotspots are odd in that one is large and features a large variety of minerals both for the CG and others as well, even cores, and the smaller is much smaller and located just within the edge of the larger Monazite hotspot. This smaller area is almost exclusively Monazite core rocks in terms of CG goals, but they are not densely packed, you may do some dry flying looking for them. The biggest problem I found early on is the "half-baked potatoes" that look as bright in the PWA as core rocks but have only rutile and a smattering of other junk. They are some of the smallest of the flagged rocks so it's easy to pass on them. Slightly larger are more potatoes (no CG goods at all) that shine almost, but not quite, as bright as the core rocks, so you need to learn the difference so you don't waste time and limpets looking at dross.
Later: Another decent though slow run at the BD-19 402 3 rings, 200T Monazite and miscellaneous other CG stuff. Looking at the status chart it seems the Top Ten cutoff point is now at about 1000T delivered, so get haulin' Commanders! I also noticed my Trade rank is getting rather uppity, about +11% per run. I started at 27% Tycoon and am now at 84%, so I'll likely be reaching Elite Trader with this CG.
