Although I use a Wagulator, I also carry three, sometimes four squeegees with me. But I can't carry four wagtails. I do like the Liquidator channel, but they don't work in a traditional squeegee (because of the angle), which is annoying. But now I've worked out a simple modification to put one into a squeegee. I have uploaded some pics that you may find interesting. The tubing in the pic is the new plastic plumbing (push-fit) system, inside dia. 10mm. I've tried other tube without success. When fitting the channel it must be pushed up toward the top part of the handle. I have not been able to upload any pics.
