I fixed the whistle problem (even on Droid, where I'm usually playing). The newfound hated technique? Normally spaced 'streams'. Stuff like this:
I can play compressed streams, and I can press most streams, but these things I just hate with a passion, they're all nicely spaced, but they play fast, and while I can hit 'em, I can't get 'em perfect. Mind it's an 'easy' map, but it's one of those things that really make me want to quit practicing songs
. I wouldn't be so put off by it if I could at least play it on droid, but I can't, for the life of me, get 'em right, regardless of how well I can perform on other songs, like

http://osu.ppy.sh/s/39325 , those streams don't work for me. Doesn't matter how I get into 'em
. At least they're not as frequent in the maps I like to play.
I'd complain about jumps, but jumps can either make you or break you, so it's a to each their own thing. Some are well done, others... not so much.
