Round edged plectrums are what you go for if you want a thick sound and picking stability at the same time.
While the classic "derlin" shape delivers fuller sound than average pointy/sharper edged picks - as the former has actually more body when hits the string than the pointy ones - its subtle roundness helps the pick sweep nicely throughout the strings without getting stuck in them. In spite of the (undeserved) good fame somehow achieved amongst shedders worldwide, the pointy picks are actually not as good at the job as they may look: beside being sonically inconsistent, the pointed/sharp edge may cause the pick to hook the strings (especially when operate transversally) instead of just hitting them and may accordingly cause unwanted braking in the picking hand as well as deliver unpleasant "buzzy" tone. The Tortex STD succeeds where the average pointy pick fails: you get sound consistency, dynamic control, significant accuracy, fluency and picking hand stability at the price of very subtle speed loss.
Beside its shape, another upside for the plectrum hereof is the material employed.
The particular blend of plastic feels very comfortable for the right hand, yet responsive and tight enough to keep the holder always in control of any stroke, even at high speed. Although its plain surface, the grip is excellent and grants remarkable grab at any climate conditions.
Due again to the remarkable material employed, the Tortex STD durability is very impressive to the point it ranks it as one of the longest lasting guitar plectrum around: even at very high rate of usage the Tortex STD stays playable and its tip, although consumed, stays very smooth and polished and free from any sort clumps or "teeth marks" that other picks normally sport on both edges after few days of employment.
Moreover, the relatively low thickness of Tortex STD in exam (the type hereof being the 0,88 mm) would grant you even more beefy sound if used in conjunction with medium/heavy gauge strings (0.10, 0.11 or harder). In fact the harder the strings the fuller the plectrum "rubs" on them.
Conclusively, I've tried million different brands and shapes of picks in my 30 years + rock/metal guitar activity and for a reason or another I always find myself returning to Tortex STD 0,88, which at the moment I consider the perfect blend between tone, comfort, playability and control. If I could make a wish, I'd love if Dunlop made a little pointier version of Tortex STD 0,88, so I could have a faster pick to opt for while keeping all the tone and consistency intact .
Tortex STD 0,88 is the force to be reckon with in the picks industries, a true classic and my personal evergreen.
