flooded v. sealed batteries [RE-wrenches]

I sit with 13 year old tubular plate fork lift batteries running this
homestead.  I like the strength and extra surface area the tubular
plates offer and the depth of cycle gets us through ugly winter weeks
whilst waiting for wind.  After 13 winters they are starting to fade-no
surprize- but I'd certainly buy them again.

For off-grid applications, where do my fellow Wrenches stand (or sit) on
the question of using L16s, say, as opposed to sealed AGM or gel
batteries?  My hit has been that sealed batteries, either AGM or gel,
are not a good choice for frequent and possibly deep cycling.  Any of
you who can guide me to some on-line links or literature on this issue?
Thanks.
