Removing twist before or after glue up?

>I'm glueing up three 6-8 in. boards for each of the four sides of a case. Each board has been edge jointed and sized to width on the table saw but is otherwise still not yet planed. Normally I would remove the twist with a hand plane before sending each of the boards through a planer and then glue up the boards. I seem to recall that Tage Frid sometimes glued up boards without removing the twist to allow the flat board(s) to pull out some of the twist when they were glued up. Then the whole glued up panel was flattened; doing it in this sequence would supposedly reduce the total amount of wood that would have to be removed thus keeping the panel thicker. I guess it would be analogous to edge jointing a 9 ft board to remove all of the bow and then cutting into three equal lengths versus cutting the board into three pieces first and then jointing. Has anyone tried this or does anyone have an opinion on whether it makes sense? I guess the real reason that I'm asking is that the boards are about 7/8-15/16 in thick rough and I'm not sure that I'll be able to get a 3/4in. panel after flattening each board.
