I've compared many materials, bone, horn, nylon, celluloid, Tortex, Ultex, and others in thicknesses between 0.5mm and 1.5mm. Also tried the traditional teardrop shape, the triangular and the sharp point, this 1.14 sharp does everything better.
First it does less pick noise, which I noticed when I muted the strings with my left hand to hear the pick striking the string only. Second, the point moves over the string faster than the rounded tip so I can execute faster tempos cleaner and with less hesitation.
Then the rigidity removes the rubbery sound that the strings used to make with softer picks. All that makes for a snappier attack that really shines when you play distortion. I thought I had a good metal tone but I realized it was not crisp as can be.
Lastly, the thicker 1.14 grips better than the thin ones, and I plan to try thicker gauges, 1.40, 1.50 and maybe 2.0 but for now the 1.14 does everything I like. I was stuck in the idea that thin picks give out more high harmonics but the thick ones give out more bass, so the sound is not brittle.
Highs are not lacking, and even if they were, only a little EQ adjustment will do, the reduced highs are not such a large difference that it's outside the normal EQ range.
Some picks are not quite symmetrical at the tip but a few passes with superfine sandpaper rectifies them and improves the feel on the strings.
