I got my Adamas picks about a week ago and they really are something. I am used to using a standard, Fender Medium and all I can say is Holy Shit!! Tone, Tone Tone!!! If you are used to a lighter pick they do take a few days to get the hang of, but after that you can never go back. The main thing I have noticed is the amount of definition they give you when you play chords but most especially in the single note lines. For example, when using my Mu-Tron III I used to have to hit the notes in the higher registers of the B and E strings a bit harder to get a solid, defined tone. With the Adamas, I get an even voicing on any string, any spot on the fretboard, with much more control over the voicing of the note or chord. It is a huge improvement and has actually changed my approach to picking a bit.
The Telefunken's are pretty expensive, but one must admit that they are very cool looking. I have always liked the Telefunken logo (and always wanted to get some vintage Telefunken-branded Schoeps mics) - I am going to get a few. Too cool for school
