I've been using Ultex picks in various gauges exclusively for several years, now. My bass and my six-strings all have Ultex picks. No need to comment on tone, durability and grip, they've been reviewed many, many times and the great opinions are justified. Only little downside was that the tip was often not perfectly shaped and symmetrical, you need a magnifier to see that but you feel a slight improvement in touch after you rectify them.
So I used to take 600 grit sandpaper to reshape the tip and 1000 grit to polish it, and I expected the same job would be needed again. But no, the first pick I took out of the bag had a perfect tip. Symmetrical, not too round, not too sharp. I thought, is it just luck? But no, five other picks were removed from the bag and the consistency was perfect.
Seems that Dunlop has improved the manufacturing process and that's great, it's safe to assume all the other picks will have a tip identical to those that were checked with the magnifier.
