I have two 200 Liters variable volume SS tank and I really love them.
No trouble with small size. But I agree that big tank could cause
more problem because of the weigth of the lid but it is not the case
with mine. I find them to be really handy for blending and no worry
for top up with the floating lid. I use them to ferment my red and to
aged blended wines. No complain so far.
