I use the floating tube as well. I have issues where the kegmenter had got 10psi and the keg Im transferring it to has the spunding at atmosphere and the transfer is almost stopped. At the start it seems to go ok, but I think that might just be when the 10psi in the keg is released. I have purchased recently some heavier silicon tube to see if that helps. The only thing I can think of is the silicon tube is collapsing not allowing the beer to come out of the kegmenter. My last resort will be to get a corney keg dip tube and cut it to length for my kegmenter. But if anyone else had any ideas they would be appreciated.
