I am in the planning stages for a set of ribbed lake pipes. I am having trouble finding the tubing. I find a lot of old dead links from around 2003 and a lot of "out of stock". I see Moon has some, but the ribs are pretty faint. It's a last resort option. https://www.mooneyesusa.com/product-p/bktfmw001.htm Anyone have pics of the original ribbed lake pipes up close?
