Haven't spent a lot of time with one yet. Thought I would give them a try. The stiffness does increase subtly when you choke down toward the tip. The slight flex on a more medium pick is something that could alter my picking style I suppose, I just haven't discovered it yet.

I picked up a Dava pick about 10 or 15 years ago. They are the only pic I use now. They feel great in your fingers and allow you lots of flexibility. They also last a lot longer than regular pics.

I have been using this brand of Dava picks for nearly a decade now. With an average of 4 sets per week (not including practice, rehearsals, or sound checks), I don't have time to worry about issues with my pick. Dava picks give me a confidence to forget they even exist - they are an extension of me. I have never dropped or broken one of these during a performance. I keep backups, but I've never had to use them. Picks are cheap but can be expensive over time. The only reason I have to get new ones is because I either give them away or lose them. These are more expensive, but you'll save money in the long haul and avoid embarrassment during live performances.

Over the years I've tried a lot of different picks. This is the only pick that I have found that actually remains in a usable position for me. Most slip around in my fingers or even actually out of my fingers all together. They fit, they "sound" good and they stay in position.
