Long time Black Jazz III Maxgrip user. They were my picks of choice but since they're black whenever I'd drop them they would disappear forever so after some searching for stiff Jazz III style picks with grip pads in more distinctive colours I found these. They're actually bigger (but by very little, although noticeable) than the classic Jazz IIIs which at first disappointed me a bit, being a fan of small picks, but since the difference is so little I didn't really feel that when playing. They don't feel any slower either, if anything I think they might be a bit faster. Haven't done any "real" testing but I think that's because they also feel stiffer. And the traction pads although not having as big an area has the Maxgrips work equally as fine. The grooves are deeper and they're more "spread" so they don't get as gunk filled and are easier to clean as well. Tone wise I can't really tell them apart, except maybe the Nylpros having louder pick noise (again, anecdotal and never really did a proper A/B test to verify).
And, just like I hoped, their color makes them very easy to find. Already dropped them plenty of times and have still never lost one
Overall, I think these are an improvement. The few negatives I pointed out are really just nitpicks that don't really matter all that much and would be far over-weighted by the positives anyway. These are my new main pick now.
