I'm not sure exactly how the Fill/Bleed kit works. Does the water enter into the side and exit the side? Do the two vertical pieces simply allow water to be put in and air to escape? If so, it will work like an inline system once filled: there will be almost no restriction. It will also benefit from the pump's ability to feed off of its own power. In a resevior system, there is a buffer that forces the pump to create all the energy at the beginning, only to lose that energy at the end of the loop. A Sealed resevior is better as it allows for the pressure to remain the same. Inline systems do tend to flow slightly higher than resevior systems as long as the restriction is similar.
