I think my "fine" blade is a 60 (might be 48) tooth from Trend, not expensive but leaves a perfect cut on MFC which is pretty much the main thing I cut. If I want to cut anything else I switch blades, the stock lidl 24t blade is actually not bad for trimming doors etc but I don't use it anymore as it's too wide for my splinter strip, I have some cheap titan blades I got for 50p each, they are smaller and narrower, I use them for ripping up sheet goods to rough dimension as the cut is about 0.5mm away from the splinter strip.
