Whatever it is has to fit in the 2 x 8D or 6 x
T-105 footprint. Too hard to change that.

I've been very happy with my Lifeline AGMs (2x8D). I've got a couple
of buddies who installed Full River AGMs and they like them too and
they cost a lot less. There are some other interesting developments
out there including the Thin Plate Pure Lead AGMs. But, none of those
will be in the running if you're looking to get the best AH/$$. For
that I think your T-105s are about as good as it gets.
