There are plenty of channeled hammocks out there serving the owners fine after years on the job. Do not fear the design.
Whipping is only needed to create a mass for the suspension line to bite onto in GATHERED end construction. Particularly the cordage of old, like paracord etc.
Whipping is a step that, IMO, is not neccessary anymore with the use smaller /stronger lines, like amsteel. I do not whip any of my hammocks and they hold me. A small rolled hem keeps the supension in check or I use the Warbonnet/Knotty small channel and cord technique.
Evolution of new products and fabrics brings new techniques, so take some of the past "hammock info" with a grain of salt.
