Low discharge AA batteries?

[Early]

Has anyone used these new low discharge AA batteries? Are they good for use in a flash?

Duracell came out with them a little over a year ago, and I can swear by them. Although I haven't used the AA's in a flash, I've used a set of AAA's in a wireless head set that eats the older nimh's. They even last longer in use.

Those Lenmars look like they'd be nice to have, especially with one the the quick chargers.
