I am seeing this type of tube design pop up more and more frequently. I've been watching the Decathlon Caperlan fltb9 develop for the past few months but it is not available in the US yet. I like the solid seat design on the fltb9 and it gets a solid recommendation from at least one guy from Ireland (norbert renaud) who I know fishes for pike a lot from a tube (and is a really good tyer - pike flies on youtube). Seeing these little electric motors that they also use for paddle boards being added to these tubes more frequently. Nice to have some new float tube options in the works.
