I chose this 'Acoustic' pack over the electric ones because I tend to prefer thinner plectrums, even though I exclusively play electric guitar.
This has been a good way to test out several types and find out that I don't need to settle for only one plectrum. For melodies and scales I tend to use the middle one like the .73 Tortex. For fast playing with tremolo picking, a lighter/thinner one like the 0.60 comes in more handy, especially with grip texture.
It's nice to have options.
The only negative i've found but didn't influence my rating because it's a cosmetic one, is that the illustration on the flex plectrum faded after a couple months. But I can only see that being a problem for the flex .73 & .88 that are alike. They're both white, so without the illustration, you can only tell them apart by feel.
