I use a thin kerf Freud crosscut blade for most of my needs. If im ripping a thicker piece of hardwood ill throw my Freud rip blade in. But my general use blade is the thin kerf crosscut Freud. Costs like $45. Works for me.
I would want it better than that, especially if the blade is squeezing towards the fence.? I wouldn't want over a couple of thou the other way, but like dead on.? I probably should add that I don't use a splitter, or any other such device.
I do the same thing my rip is their glue line rip and I have been real happy with the freud blades. ?I have had the ones I have now for 5 years and only sharpened them once. ?Keep them clean and don't abuse them and they hold up well
If I were to get a combo I would probably be looking at the Woodworker II.
