IMO/IME, a false bottom (especially one from NorCal/Jaybird) is the way to go. I have one of the 15" with the hinge, handle, and hole from them and it works excellent.
Of course, I only have the false bottom in my mash tun keg, not the boil keggle...
BTW, the false bottom means the entire diameter of the keg is your manifold/filter element. Not just one hose running a short distance.
