I liked the standard Tortex 0.88 (ads a nice rounded sound to your playing) - and thought the idea of a triangular/three sided pick looked interesting.
To my fingers/hand (glove size 9) and playing style (acoustic guitar), these are a bit too big - a bit clumsy one might say.
BUT I think they could be very good for bass - have not tried, as I don't play bass, and the 0.88 is probably a bit thin for bass.
As I still think the idea of a three sided picks holds some interesting quality, I will try to make them smaller to see how that works.
Could be nice and helpfull, if Thomann gave measurements to picks that fall out of 'Standard size/shape' - like these ones and some of the picks for Jazz ;)
