cordless framing nailer

I've resisted buying airless in the past because all my framing guns use 28 degree nails and the Paslode Impulse uses 33 degree - I didn't want to carry yet another range of fasteners. But now I see Bostitch has a cordless framing gun on the market and it uses 28 degree nails. Coming up soon we'll be back framing on an institutional building with a zillion little rooms - backing and blocking with cordless saw and nailer would be a real time saver. I've used Paslode guns occasionally over the years and found them to be a bit fussy if not kept meticulously clean. Anyone with the Bostitch gun like to do a review or a comparison?
