the fact that you memorize a map doesn't make it unimpressive (though peppy seems to think so now anyways)
I agree with XK2238 about FL stuff. It is possible to train your reflexes to play FL, i got better and better playing with it, BUT it is only readable at low bpm taiko maps and low SV/BPM converted ones. Also depends on the ammount of notes in the map, since the visibility area gets smaller when you reach 100 and 200 combo. Otherwise FLit is useless on taiko maps and imo should not count on them, cause memorization is not a competitive type of skill.. ANY player can memorize a map, it just depends on the ammount of attempts each one takes to do it. But there are players who can memorize easier than others and can't play hard patterns with good accuraccy or can't read high BPM on taiko maps.
also up to 150 to 160 bpm is entirely plausible to sightread at 200 combo depending on the density, perhaps even more
I'm also personally for standard converts as not counting them feels an awful lot like saying they don't require skill
edit: also to clarifiy I'd give a score more pp the more impressive it is rather than judging by how much skill the score might've taken, I don't feel like the latter is even possible
