i usually find that when i use dominoes i can get away with 2 clamps instead of 3 or 4 for a rubbed /biscuit jointed glue up
that extra clamp left over allows for a few more glue ups to be done,
a while back i had to make up a large batch of window boards. they were 2 normal pine window boards glued and dominoed together. i added a few pocket screws to hold everything while the glue set
i clamped everything normally then added the screws. i left one clamp on it just for extra security but i think that was over kill.
i also find that when i domino the joint i never have to worry or ever check the joint . i know its perfect. i used to have to move boards around adn clamp them in funny ways to get the joints flat.
