Good Practice Files

[SubaruPoptart]

So, I'm looking for some good practice files for jumpstreams. Used to be able to go mid-70s consistently but since I haven't been able to play on a relatively good keyboard since July, I got an metric buttload of rust so I gotta shake it off. Ended up unlocking Otaku Speedvibe Oni through a random play of Bloody Tears, ended up blackflagging Otaku about 5 days later.

Now I try to do Otaku I get tripped up at the little jump-chain triplets. Trying to get back my jumpstream-ish speed and just jumpstreams in general cuz I'm pretty bad at those as far as I can tell.

There any good practice files for those of that speed or around there? Cuz I can't find any right off-hand that I can remember.
