I bought these with the intent of trying new strings, to know which fit me the best. I have been using them for a couple of months now, and I have started to notice it's strengths and weaknesses.
* Great for slapping/popping with ease.
* Are very easy to play with, especially if you wanna play quickly.
* Not suitable for tuning down. Even going just a half step down, they feel like spaghetti. Drop D works fine, but is still not recommended
*Has below average tuning stability.
In conclusion: If you do a lot of quick playing (a la Jaco Pastorius) or do a lot of slapping stuff in standard E tuning, these are great, and you should consider them. If you like to tune down your bass to alternative tunings (drop D, Eb standard), get standards or thicker instead, as these wont be worth your buck.
