Any deep bend will add more friction. You can give it a shot and see how your cable works. I can say that when I installed the noodles that came with my v-brakes I was suprised at the added friction. My diacompe 287-v brake levers came with two additional noodles meant to be installed at each brake lever to help route the cable as it exits the lever. I skipped them beacuse the add friction was too much IMO.
Give it a shot though the only way to be sure is to try it.
