Most burners will do well with 16x +R Verbs, especially when burned at 12x.
As Kent, I've a Pio 111D flashed to the 111L & it burns very nicely thank you. As do my 2 Benq 1650s & my Liteon 1635S.
You'll find that the Liteon LH-20A1H burns these very well at up to 18/20x so at 12x or 16x you should get very good burns. There are some scans on this page
