I use the Meguiar's foam pad. If it's too big for the tub, I just swipe half of the pad inside. The other half of the pad I hold with my thumb. THat's how I apply all my waxes so my pad doesn't go flying

! I hate flying pads

. I also do straight lines, maybe circles sometimes. Unless the wax needs to be dried to a haze before removal, I just do WOWO. I'll wax a panel, then wax another panel, and wipe off the residue from the previous panel, and keep going. If it's a dry to a haze type of wax, I'll wax the whole car, and buff off starting from the first panel I waxed, and go in order.
