mc9mm, what do you mean by "really fast"? Like sixteenth notes at what tempo? I find that at tempos that are somewhat fast, like 16ths at 110 bpm, there's no problem with the sharp edge of the pick "grabbing" the strings, but I use a pick where the "sharp edge" is somewhat rounded (I use Tortex 1 mm, the light blue ones). I also have picks that come to an actual point, but I don't like the feel of them. My advice is that unless you're going for the "notes so fast and blurry it sounds like a wall of sound", kind of like "Jupiter Proximity" by Bofatron Sofasaurus, you should use the sharp edge of the pick for clarity and definition of sound.
