I'm with everyone else that there's all these different methods and fans of each (how about the 2x2?).
Personally, I've used the v-set (weave a matics?) and channel and MUCH prfer the channel. Just seemed to make more sense to my dogs, ALWAYS had speed in the equation, and my dogs trained with it do great. Understand the poles as one continuous piece of equipment, not 12 separate torturous 'obstacles' that need to be lured/coaxed/prodded and pushed thru.
Here's a good sites with some methods:
AND, have to say, I recommend starting to save up to get some 'real' metal based weave poles. Cause if you are training properly and your dog IS driving thru those poles fast and crazy, anything less than a metal base will have those vertical poles flying all over the yard everytime. So for a 1 second weave performance, you then spend 3 minutes setting everything back up.
This first photo is when Bretta was about 18 months old, in our training place, and these are the chute type weaves about 6" apart at the base (look at the metal laying on the ground). Look at how the poles are 'bent'.
Here she is a few month later on regular closed weaves, same thing:
The other thing I want to add about all three photos, is LOOK AT WHERE BRETTA IS LOOKING AND FOCUSED!!!!!!!!!!!!!!!!!!!!! Because it's not on me. It's not on my hand luring with food. It's not on my face. Or my leg pushing her in and around each pole. Her only concern about me, isn't about the poles, it's that I'm somewhere in the area cause, at the end, as she exits, when she's done with ALL the poles...................that's where THE TOY gets rolled out ahead of her on the ground for the real reward.
