This collection is what I used over the past 2ish years for warming up. It has everything from speed to flow to single tap at like 180 to like 280 or something. Just whatever I felt like using for warming up and some stuff I still haven't played as well so it never felt like I was retrying the same stuff everyday. Uploaded for my homie trying to get better at speed so have fun. There are other modes in there but just ignore them cuz I sort by artist and just add entire beatmap sets to collections, not specific diffs
