If you have a single-nozzle printer, and you can do CAD, then consider designing your own supports in CAD. Test various concepts and dimensions on a small testmodel, before doing large models.
Standard supports are good for standard situations. But special cases might be better off with custom designs.
A few examples:
Pink and orange supports with custom brim to prevent them from getting knocked over. These are stable and solid supports, so I can grab them with a plier and wiggle them out. This model is way too small to get in there with a knife.
Concepts of supports, to minimise damage to the model. These require good testing: if the gap is too big, the model will fall off. If too small, the model will glue to the support, and separation will be difficult.
Free hanging supports, not going down all the way to the bottom, and thus not damaging the lower parts.
Front view of these free hanging supports: they stay in place by the stringing of the material. This makes them very easy to remove (way easier than standard supports). The ribs on top are 0.5mm wide and high; the inverted stairs at the bottom are 1mm wide and high. This model could be printed without supports, but I want more accuracy, since another part has to slide accurately through the opening. The tabs on the side of the supports do almost no damage to the side walls of the model.
Printing tiny vertical models often causes this effect: the filament can not solidify due to the hot nozzle continuously sitting on top of it. So it deforms. Layer-adhesion and stress-concentrations could also be a factor. So you might want to design supports in such a way that they move the nozzle away for some time, and allow the model to cool (or print multiple models at once).

Please keep in mind that support structures in FFF and inverse SLA serve different purposes.
In FFF it prevents the slack of overhangs while in inverse SLA it prevents the printed object or parts of it to detach from the build platform. For the latter, well distributed touch points are enough while for FFF a surface (interface) is needed.
I recommend you look into getting a dual extrusion printer (that allows for the usage of a water-soluble support material) as the Ultimaker S-Line for your application.
