I recently bought these bad boys because I've been wearing down a great number of regular Tortex Jazz 3's, as well as Petrucci Ultex's.
I've tried metal and wooden picks, but they're not my thing, so I naturally went for these.
Being used to "regular" Jazz III's, I must say these feel even better.
The grippy surface really help with keeping in place, without being overly grippy.
I feel the need to point out a play a lot of metal, heavy drop tuned on baritone strings, and these picks feels like they were made for that.
I'm always a bit weary with picks thicker than 1.14mm, but despite these being every so slightly thicker, you dont really feel it.
I can definitely feel that they're made from a more durable material though.
They dont wear down as quick as Tortex, and are a bit more durable than Ultex.
So, if you're like me, and are on the market for an upgrade from the old Tortex Jazz III's, or just wanting to try something new, then these are worth a try.
One thing to note about all Jazz III's: They're smaller than "regular picks"
