The Jazz Max Grip Carbon is a very cool little fella. I wasnt a fan of smaller picks but when I tried this I was amazed. It feels like you are not holding a pick but whatever you want to do with your picking hand actually happens instantly and you reach the strings somehow faster compared to larger picks. Thats how it feels at least. Hence I prefer these picks for mainly lead and solo work. They do make a difference in my opinion and feel faster for sure. For rhythms they feel good too but it feels like you end up missing a bit of the punch. For stuff that require extra precision (like meshuggah's bleed) they could be very cool. I also think these were the picks that did color the tone least among the picks I tried. Other than that, they have tiny zigzag line figured textures for extra grip. I dont feel like I need extra grip but they dont bother me nor they hurt my fingers as it was claimed by some people.
They are all very durable and the carbon fiber one seems to be the most durable.
I hope this helps but at the end of the day picks are picks

hehehe
