Like pimple pounder said, the flags are good but the benefits have some limitations. First off, when I trolled in line boards I ran 17lb Trilene, braid is a pain with inlines because it slips through the clips, especially the back clips that actually work the flags. If you are using mono, just make sure you leave a few inches of slack. You will need to adjust the tension when going from a crank to a weight or diver and they don't handle TT40 all that well. Honestly I think that they will help you out. If you have the tension set right it's easy to see even with a small fish on because the flag will be ever so slightly further back than usual. Good luck!
