For everyday performance I always use my Blue Chip picks - TAD40 and TAD50.
Just enough mass and just enough "feedback" into thumb and finger.
I was given some of the "primetones" when I bought my Waterloo in 2016. They are too inert for me, I still have one of each type but have given away the rest.
Well done for Dunlop trying to emulate BCs but really not anything like vespal.
During 2107/8 I experiments with trying to improve Dunlop ultex & tortex 1.14 m/m and D'Andrea Pro-plec 1.5 and Fender extra heavies.
They ll need to be polished, bevelled and repolished and maybe have some Wegen style hole grips.
The Tortex are easiest to improve, the Ultex hard to do but good ersults, D'Andrea and Fender - celluloid so can melt.
