Yeah the fuel cells are the non shield version of the Batwolf. I have the tacos, offshoots, and fuel cells. The tacos/offshoots are definitely bigger than the fuel cell/Batwolf. To me, the fuel cell/Batwolf is more comfortable for long periods of time due to the arms straight and they don't dig into my ears nearly as bad as the tacos/offshoots.
If you're coming from a flak, you would probably prefer the fuel cell/Batwolf fit better. Not nearly as bulky on the face as the tacos/offshoots.
