Soft Plectrums

Hi

Is it possible to get a soft (possibly silicon based) plectrum? What I am looking for is a plectrum that sounds like a finger is being used to play. There is a very obvious transition in sound when transferring from finger-picking to using a plectrum for lead/solo work. I can play a little bit with my fingers for the lead but do not have the speed and accuracy I can get with a plectrum.

I have found some nice plectrums around in my search so far, including a metal plectrum that gives a unique sound, but have not found anything that comes even remotely close to sounding like a real, human finger is being used...

Anyone?

Regards,
Luke
