Flexbone is extremely expensive for what it is .
Ditra and tile , you will be fine, your ufh will help with the drying time , most tilers have tiled onto green screeds over the years with no problems .
Or spend a nice weeks holiday money on flexbone .
Which is basically ditra with some scrim stuck on it (it’s actually not at all like ditra, ditra would be much more expensive to manufacture than flex, but is a good few £ cheaper, ps there’s also cheaper matting than ditra as well )
