I switched to the .88 tri-corners a few months ago from the Dunlop Primetone - it became my favorite pick. Recently I ordered a sampler pack of 4 different thicknesses. I thought I was going to like the thickest ones best but I totally fell in love with the .71s, the thinnest. It brings out a cheery brightness in my Goodall that has me floored. I ordered a bunch more, thinking I was ordering the tortoise shell picks. A few days later I realized I had ordered the solid dark colored ones. I was a little worried, but it turns out they feel and sound about the same as the tortoise shell variety. I hear no difference. I'm so delighted with this pick.
