I don't use modern slicers but Skeinforge has an option to not cross perimeters if it can be avoided. I use that for stringy plastics. I would assume other slicers have a similar option. I don't use PETG because it sticks to the nozzle too well and won't bridge because the nozzle rips up the last thread it laid down.
