Dado Blade Newbie - which is best the stacked kind or the wobbly kind? -...

[eetrapnoel]

...sizes? - speed? Hello I just purchased a used 10" B&D FS210LS table saw (light duty I know), 5/8" arbor, 5000 RPM. The instructions do say it is dado capable. So, I see the wobble and stacked blades available. Some dado blades arent rated that high of speed which I think I can control with a variable input.
1) What about the size? Can I use 7" dado?
2) Which do you guys prefer the wobble or stacked?
Just trying to be safe, thank you
Thank you for the good advice. I have to leave this for the voters.

1) I can make multiple passes useing the same normal blade and I might get great results depending on my skill.
2) I can try out the stacked blades as they might be more accurate than the wobbler as answered from experience. Thanks for the encouragement.

i don't care for any thing that wobbles. especially spinning that fast. i don't even use a dado, i make a series of cuts, takes longer but i've gotten excellent results
