Now after years of trial and error my guitar playing has lead me to a terrific place where less is most certainly more.  I used to use heavy nylon picks and bang out rock & roll with heavy strings on my guitars.  These days I have settled on a more nuanced approach to guitar and I have set the action as low as it can go and remain buzz-free.  I now allow the guitar to do all the work and this .46mm nylon pick suits me at this stage of development to a Tee!
