Dear Grumpy, Battery technology should be irrelevant since the utility buy-back price covers not only the cost of the electricity but also the battery wear (if over time they eat away half of your meager 500 cycles, they will have paid you back half of your LA battery pack), plus a bonus.
You might object that having to replace your battery pack more often is an inconvenience, but I submit it is in fact an advantage: since battery technology advances, at every battery change you get more juice for the same price don't you?
