Our club used to use a nice football field liner. Was a pushcart with a hopper/lid and it had an adjustable flow and everything. Made it very easy/quick to do. We used to use flour to line the courses and someone forgot to remove the flour once before we stored it. When we went back to it there were maggots living in it so it got chucked.
The unit we had was just like this: http://gmocart.gmotion.com/store/me...eldmarking
