Was just wondering if coax feed with balun at centerpoint would be better
than ladderline feed with balun at tuner output (and no, my tuner doesn't
have an internal balun).

Tuner-balun-ladder-antenna is better. Lower losses if
the tuner is doing anything, i.e. antenna is not 50+j0 ohms.

Since you are considering using ladder-line, you must be thinking a little
about efficiency; wouldn't ChokeBalun-BalancedTuner-ladder-antenna be at
least as good and maybe even better?
