I've been using these for a very long time, and am in no hurry to switch to anything else. As with most things, and picks especially, it is a matter of taste and preference. I like these over the "standard" shape because they are a tad bigger and a tad pointier. More surface means more to grip, which always helps, especially in live situations. They seem to be made of the same material as standard dunlops, just slightly different in shape and size, last for a good while and I like the neon turtle. I guess the only "con" would be that once sweat is involved they become very slippery, which is true of many pics minus the ones with a convex grip. Again, as many others do, I just scratch the upper part of the pick with something sharp to form criss-cross grooves, so that gets rid of the slip problem. Also I'm fairly sure that they last longer than standard tortex ones - those would always end up as ovals, while these Wedge ones never get quite so eaten up. Good picks, do recommend.
