I normally carry a PLB (fastfind), HT (ft-60R) Cell Phone & gps. My partner, Gloria is also a ham so we use our radios a lot. If we are hiking in remote areas, I leave the vehicle radio (D-700) in crossband mode linking us to a suitable repeater. If we are in "self rescue" areas like the nearby military training area, we make sure there is someone capable of assisting us, monitoring the repeater. Not all the areas are covered by repeaters though.
The PLB is the real "last resort" item. The other gear provides other service, but is not intended as primary safety equipment. That said, I would try to get assistance with all the other gear before resorting to the PLB.
I guess I have been packing this stuff so long that I really don't notice the weight.
The PLB has really eased our minds a lot. This is especially true when one of us is hiking alone.
