Well, I've made some progress and got much better results - not great, but much better. When I was printing with 0.4mm nozzles (PETG) I often turned the cooling down to zero to get the material to flow together a bit better - it seems that this isn't a great idea when printing with 0.8mm nozzles. Maybe the thermal mass of the fresh layer is a bit greater (although it's the same thickness) anyway, it seems that the nozzle picks up on the layer too easily and causes that frilling effect. Turning up the cooling flow to 75% cured most of the problems. Slowing down the print from 60 to 50mm/s also helped (it is laying down four times the volume than 0.4mm nozzles at the same speed after all). I also reverted to a hotter baseplate (85DegC) and my preferred setting of a super-slow initial layer or two (10mm/s). I then switched to 40% infill (Gyroid for a laugh) and increased the outer wall thickness to 2.4mm or 3 wall passes - the overhangs are still a bit rough and the surface feels more like paper than the silky smooth plastic feel I usually get - put the part is functional at least.

S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
