Got some leather pics... nice on the acoustic with flats... but they are not very stiff so slow goin' which again is fine on the acoustic.
I also have some wood picks... warm and no real click, but rigid.
Agreed 0.8 is good to give the string a twang, rather than a clunk with a 1mm +
Although I use JD Jazz III as a hangover from skinny strings, love the size and feel and just use the tip.
