I recently picked up a brand new Orion 3200 and the IR numbers are so high I'm not sure I will use it at all. They are typically around 4.0mOhms. As socket said I don't usually use batteries once they get this high let alone run new packs with this high of IR. It's a bit frustration since they advertise low IR....nothing you can do I guess.

Socket can you comment on super shorty packs? I had bad luck with the 2800 but would like to have a pack that is around 150grams or a little lighter would be ok. This way I can fit it under my rear waterfall farther than a full size and also use an under battery weight for super low cg. Thanks!
