Trying a run on CADO degree 6 from 0 to 200k, incr=60, nq=7776.
I set rootopt at 35 both last run and this; compared to the first phase, root-opting takes little time so it seems a good risk-reward to set this rather high.

I ran the CADO sizeopt on the msieve stage1 hits that yielded my first poly and got a better poly.
