Any tips with jumps/jumpstream?

[T)r6g0n]

Hello, I have been playing FFR, and I can do streams pretty well as long as they don't get extremely fast, but once they through jumps in there, I get thrown out of the song almost immediately ... It becomes seemingly unreadable and impossible. Besides the average tips of "Screenshrinking" and "Practice practice practice" or "Spread" and all that, what do you suggest? My playing style is best 3-fingered, left index on left, right middle on right, right index on down. Also, I am having a problem with the up + right jumps in a stream, because my middle finger taps up instead of my index. My right index can never goes up, for it doesn't feel natural. I've tried moving my left finger up, but I can't move it back fast enough. I have no intentions on switching to spread, because no matter how hard i try on spread I feel like I am being introduced to Dance Dance Revolution again. The main song I am trying is 20031023... Any tips will help... ty
