I've got an 8" twist 6-284 on a 98 action and have the parts for a 10" twist 6 Rem AI - just haven't got the barrel threaded and chambered yet. Because this is a slow twist I am thinking small case. Maybe my thinking is goofed up, but that's the way I think. I would say 6-250 would be the largest case I would consider. Leaning hard toward the Dasher, just gotta get past the non feed hurdle in a repeater.
