If you bury all of your driplines then then you wont have any problem with raking. You could always just use a leaf blower instead of raking. Sometimes driplines are the answer. People have a tendency to overplant flowerbeds and wind up watering part of it by hand or having to move sprinklers around. Adding to a dripline is easy to do. I used to hate working on driplines and avoided them. But once you get the hang of it. No worries. I love the staked stream bubblers myself. Goodluck!
If I can't fix it, it's broken!
