I suspect that whatever changes to taste that blind burrs will add, it will be imperceptible to human taste buds. That seems to be the consensus as far as the results that 102mm mizen blind burrs have produced vs 98mm mizen burrs so far anyway.
Anyway whatever the explanations of why they are so good etc., grinders like the kafatek are just beyond my budget for them and may as well be unobtanium. In this regard I am just glad I managed to find a used 98mm grinder at a good price and will have to stop my titan grinder ambitions at that stage!
