I've been using Tortex picks every since I started playing guitar a few years ago. I normally play worship songs where it is mostly strumming, if I do need to pick then I just use my fingers usually. I started with the .73mm (yellow) and also the .6mm (orange) Tortex picks. For strumming only these .5mm picks are great, but they are so thin that they do not offer much versatility otherwise. I think my next purchase will be for the .6mm orange picks just so it offers a little more versatility, not much though honestly. Best bet is to have various types of picks on hand. Overall though these picks are great, they don't slip and are pretty easy to find because of the colors. I haven't tried many pick brands and I don't really want to.
