one would keep in mind that refilling numerous times can cause wear to the rubber seal in the small bottles and they may eventually leak (not a good thing for those stored in a locker). A bit of synthetic grease wiped on the filler valve needle helps in this regard. An added solution is a short section of perforated white pvc pipe fixed to a stern stanchion in which the one pounders can be stacked for outside storage - I noticed a number of these setups last winter in the Bahamas. We have our stern grill plumbed into our main system but still find the small bottles useful.
