If you are new to fully bent pipes, I'd just say, with many/most, the pipe cleaner just won't bend clear into the bowl. Just clean it as far as it will go and keep on truckin'. Clean that last little bit now and then, and don't worry about it. If you have a problem with moisture, for example if you clench a lot, these may not be ideal, a little more saliva may accumulate and give a gurgle. I don't have many moisture problems, almost none that a little tamping won't cure, but just FYI. I too love straight pipes, and could happily do all of my pipe smoking with straights, but if you find you enjoy fully bent pipes, they are a pleasing addition to the stable. I'd really miss mine, especially the Oom-Paul and the Ferndown, and my first pipe, a Tinder Box fully bent pot. I like the Hungarian nomenclature for the Oom-Paul, since Kruger is not a sympathetic historical figure in my mind. But his pipe selection was pretty good. Stalin liked Royal Yacht, and I don't hold it against the blend.
