I've tried many picks various companies, having a problem with dry skin and keeping a firm but light grip can be difficult to achieve, these rubberised work really well for me but it is a shame the rubber is not longer lasting - hence only four stars - If like me you do not restrict picking to the only the tip, the sand version can produce some unwanted sounds hence I prefer not to use those. The flex and thickness produce a nice round tone (to my ears) and I'd recommend any players with a grip problem such as mine to give these Ibaznez picks a try. As usual excellent speedy service from Thomann, I'm especially impressed by the fact that they got these picks in stock at my request.
