I use the yellow Dunlop Tortex. i think they're 0.71mm, but they might be 0.73... or are the green ones the 0.73? Anyway I use the yellow.
How did you guys arrive at your choice of picks? For a few years as a beginner, I just sort of randomly picked a "medium" gauge (much like the green Dunlop tortex), but one day I decided to be a bit more conscious about it, and I bought a dozen each of the white, yellow and green dunlop picks (I'd already decided that I didn't like the super thick stubby ones nor the really thin ones by trying them a few times.)
Then I played with the white ones for two weeks, then the yellow ones for a couple weeks, then the green ones for a couple weeks. (The green ones were pretty much what I had been using from the start, and what I thought
I would prefer. But, turns out I actually liked the yellow ones the best.
I just mention it because I thought I knew what I liked, but when I actually tried a bunch consciously trying to see which one I liked without deciding in advance, I got surprised.
Edit: Hehe. I just looked at the poll results. Not what I was expecting to see, man you guys use monstrous picks.
