this is kind of an "out-there"

suggestion but this is how i learned to play pick style very, very well. as well as still being able to keep up with my finger style and slap bass.
i started bass before i played guitar. and before i picked up a guitar, i only knew how to play finger style on bass. then (skipping some less interesting parts) within a year's time i learned to play guitar very well also. especially lead since that's what i was most interested in. so, long story short, when i pick up a bass now, i kind of pretend it's just a giant guitar i'm soloing on since with a lot of guitar lead, you focus on one string at a time.
so my suggestion is if you know how to play guitar at all, take what you know from lead picking in your right hand and apply it to your left hand bass playing (opposite if you happen to be a lefty

) alternate picking will be tough but if you keep it all in your wrists, it should be a peace of cake soon. good luck with giving it another try. personally i love pick style and i think it gets a bad rep.
