what's interesting is that the Trojan "solar energy" batteries, which have claimed much higher cycle life (2-4X) than the regular trojans have

a) noticeaby lower initial SG spec than "regular" deep discharge counterpart batteries, about 1.26 IIRC
b) A corresponding decrease in AH spec's for the same weight. (As I would expect given the lower initial SG)

So, like so many things it's a tradeoff, what do you value most? Long life, or more AH/lower initial cost.

More AH for me. As far as long life, I'll be happy if they last 5 years. Though considering how they're babied (7%C charging, 1 cycle per month max at 50% SOC or higher, equalized once a year, top charged once a month, always on float unless the IOTA cuts out because it can't handle high temps), I think they'll last longer than that.
