I've tried all sorts of different finger picks, since I play mainly fingerstyle on a Taylor 314CE. The only ones that I found marginally acceptable were the Alaska Piks, but even those I only use as a last resort. Some fingerstyle players use artificial nails which I've tried and they were the closest thing to real nails for being able to "feel" the strings while you're playing. Although, they take more maintenance to keep them in good condition and can be rather expensive, since it's best to have them applied at a professional salon. I've also tried various nail hardener coatings that you apply like nail polish, but none were durable enough and would chip after playing for just a short time.
One of the members (Phill Williams) mentioned using superglue on his nails and that actually works very well. It's essentially the same type of glue that they use to attach artificial nails. I've been using nail glue for for the past 2 yrs and it's been working pretty good. I just apply a thin coat to the outer half of my nail, since you don't need to coat the entire nail. Since I also use a thumb pick, I only apply it to my index, middle, and ring fingers.
