Only suitable for E-Bass

I have begun to play bass and I've ordered this picks set to try calmly alls strengths can (different days forms, etc.) I've got a couple of buddies, play the guitar I've also plenty of grateful consumers for the picks, the I do not need.
The following picks I have found in this package:
0,58mm: 2 times yellow, red 2 times, 1 times purple, green 2 times, 1 time black
0,71mm: 2 times purple, green 3 times, 2 times black, white 1 times
0.81mm: 3 times purple, green 3 times, 2 times white

For my bass thinner picks are useless, for me personally (Basser = Grobmotoriker ?! ;-)) the leaflets are likely to be a little bigger (the length of which corresponds to the diameter of a euro coin in about) but with the 0,81ern I can start something.
Even for the guitar (I tried it) I find the 0,58er personally to "wobbly". I want to bring to the strings with the picks, "Drive" and for that I have with the thin leaves no constant pressure on the strings.

Again? No, because for me the picks have served their purpose. I now know what I need, but for a guitarist (I guess not in the Heavy-corner at home) ... why not. Is anyway everything a little matter of feeling.
