As I'm slowly progressing towards more difficult files, I have a big problem with jumpstreams and especially mixes of single notes with jumps/hands in streams (don't know what those are called). While it seems like every hard(er) file has those anyway, like 95% of them are way too hard and fast. While I can sight-read up to 130&140 bpm 16ths (not much, I know, but it gets better

), as soon as jumps mix with 16ths I die horribly^^ it's kinda doable if the jump sits on the quarter notes, but if there's a 16th jump in between, I just can't process it yet.
Could you suggest any files that have that stuff in particular (any other advice is appreiated too, of course!) but not "too fast"? That is, playing on 0.5 or 0.6 rate just sucks sound-wise, the songs lose the enjoyment-factor. It's OK for those high-pitched, sped-up songs though, since the voice just gets normal when lowering the rate. I feel like there's a gap I have to overcome, and once I did that I can (hopefully) enjoy a whole new variety of songs.
Thanks!
