if your saw is mains then saxton up to 64teeth iff its battery then up to 48 teeth would be my choice
in general a new blade with 24 or 36 will be fine for a few thousand 2x1" sized mitres on pine
i do have a 100 tooth that i can use on my table saw and the results are crisp clean and smooth but as you are around doubling the load over a 60 tooth the load is greater and rate off cut slower
at 8½ "you need a "negative rake blade" of at least 80 teeth, and never use it for anything other than the finest cuts, hide it away from feckwits
important - look for "negative rake"
these make the cleanest cuts
and don't be fooled by cheap very thin blades, go for 3mm+ they are more rigid than cheap 2.5mm
and only ever use it for the very finest of cuts, take it off the saw after use, clean it, spray it with oil, wrap i in plastic and hide it in a dry place.
