Possibly the best quality/price ratio out there for picks. Using them mostly on acoustic 11-52s and electric 10-46s
Only con: when the picking hand starts sweating, I need to keep adjusting the grip so as not to drop it. There are some picks out there with ribbed/studded grips, but I feel they become uncomfortable after a while so this grip-adjustment is just a minor issue.
Pros: really long lasting, very nice balanced hardness, good for both picking and strumming. The pick attack sounds bright and slightly round. Hope this makes sense. :-)
Would also recommend the H versions of these, of which I still have some in good shape, bought in 2003.
