2008 year model was much better
The previous model (2008 BD Momentum AL) was a true all-arounder. You can put the 2008 Momentum AL on and off easily w/out need to take off crampons. You can put it on and off w/out need to move your feet. You can gym climb or move outdoors and climb some trad or sport multipitches with it. Alpine climbs, ice climbs, mixed climbs - whatever you want. It was simple and it was great.
The new model has one-piece leg loops so you need to take off your crampons to take it on and off. And you need to step into it to put it on - an awkward and tricky sometimes.
It's still a good comfy harness for gym and outdoors rock climbing. But it lost a versatility of the 2008 year model.
