How to equalize byobu vertical split screen size

Note: I may be leaning on an XY Problem ; feel free to steer me to a more ideal approach. > I want to keep an eye on multiple remote log files in a small-yet-legible font,
**not so much analyzing content as peripherally noticing sudden bursts in activity**. I'm trying to create a Byobu script to tail log files on six remote servers.
I'm used to Vim, but Byobu calls it a vertical split: Scripted splits chop existing terminals in half, rendering each split smaller, leading to create pane failed: pane too small and a window with vanishing perspective: I'm new to Byobu. There's surely a way to select a different pane, execute a command, then split, but I can't seem to get the syntax (order?) right. I expect there's also a command to just "equalize" all panes at once. That would be even more handy. This question has the manual, unscripted version of what I need. Years ago I used GNU screen similarly, and it worked great--except using a GUI all day conditions me to use the mouse, so switching between terminals feels clunky. Maybe screen is still the smartest solution. Or tmux? I'm not married to Byobu's chyron readout. As windows split they divide by 50%, so I'm willing to accept eight terminals if the even halving leads to a smoother execution. Thanks in advance--any thoughts?
