I've recently used some James Yeahfield's signature picks, and comparing HB's to them is... well, Papa Het's ones are far better in terms of feeling and - what's as important - sound. HB's do produce some not good sounds that Het's do not, and their durability is... questionable to say the least, as I've played some of them for only 3 days and they already seem to wear off, so I switched back to Hetfield's, which, even after being played for a month or even more and while actually being worn-off, appear to be still preferable.
