I haver never used guide wires in almost 15 years of doing agility, but was recently convinced that comboing them with channel weaves was a solid errorless learning option. A friend had these so I was able to see them before purchasing. They are a bit fussy to put together, but once you get that over with, they are great. I have only had them a few months, so we will see how they hold up over time (the clips themselves are what concern me), but so far I am more than happy that I got them! My young dog has amazing weaves already, and I am glad we used the guides as part of the training process.
