Hi niko, also if you're getting things that look like they're artifacts from long and skinny polygons, you could try the aspect ratio control instead of "Divide larger than".

That will force divisions on polygons that are more than a certain width/height ratio. Like if you put in 10 for "Aspect ratio limit" any UV quad that has one side more than 10 times longer than the short side will get subdivided.

It's pretty helpful for your case for the problem areas, with making a lighter mesh, like this:






But really I would not hesitate so much to just use "Divide larger than" and dice everything up pretty finely.
