    I have no idea what the max load is for the table, but that much weight isn't going to damage it or anything. It will increase machine wear, and will slow the machine down a LOT trying to accelerate...

    I tend to like the profile (half-round) bits better. It seems to be a bit more commonly preferred as well, but it's personal preference depending on what type of cuts you do.
