I learned using 7+* unranked stream compilation maps with HT improving acc on them.
Low ar reading it's also helpfull to stream well.
Search for stream compilation.
There are compilations of normal maps what have streams, only streams, deathstreams, spaced streams l, tech streams...
There are some good ones at osusearch and bloodcat. I recommend Mazzerin maps with HT. Are not usuall "complete the rhythm" streams, so it will force you to actual read the streams.
What's your biggest problem? Aim them? tap? read?
If you share a replay on a map where you usually suck, i may know what stream maps should i link you.
At you skill level general stream maps may be useless, since you probably played tons of them a couple times. So be more specific. 120bpm finger control maps? 270bpm deathstream maps? 240burst? 160 long streams?
Maps with tons of bpm changes?
