I have ridden them all
redz, swiss, bronson, indy, spitfire, flip...
with shields, without shields, rusted, busted, silent, loud, dirty as a whore, highly maintained...
once you put it under your feet they all roll the same
they tell you about tolerances and polishing and triple steel race finishing, but after one session all those tolerances are launched in the outer space
this is my conclusion after many years of obsessively trying it all
