I have occasionally used both together in the same stick. Two 6' B-Lite poles attached above three 4' FG poles (24' total length). The B-Lites seem to flex slightly more, but they have not been a problem at all. I have never used the FG poles alone, and have always started jobs with the B-Lites. I've used them with the Jameson big mouth double-pulley pruner as well as a Hayauchi saw blade.
