Im a pretty good canvasser myself, its just easier to buy one, and work from that, I intend to keep the other for now, and just do a small amount local, unless there is a chunk for sale, increasing it when it suits
You know what its like with your own work, its usually tailored to fit. The round involves no collecting at all as that is how ive sorted it over the years, so although its 160 round trip its still viable.
