A friend introduced me to these and they look great, so I ordered a few in different sizes. It might be my thumb technique, but I tend to pick with a more forward action, so the side action required to use these well doesn't really come naturally - I can see that if I cam going to use them I'm going to have to re-train my brain and hand into a slightly different position, and the reality is I'm probably not going to slow myself down to be able to do that. We'll see...
