I concur!
although you will keep the caps in the flash unit in tip-top condition,
they _are_ leaky, and so the flash charging circuit will need to top
them up to full voltage every minute or so.
You'll have this going 24 hours a day, seven days a week.
If you want to preserve your electrolytic capacitors, the best bet
is to make sure you charge your flash by popping off a couple of
full (manual) bursts every three months or so. This will be sufficient
to keep them in top condition (it is for implantable defibrillators).
