I use these strings on my Warwick AS Steve Bailey 6 string fretless bass.
The string set comes packed in a airsealed plastic bag, so that the strings are as fresh as the day they where made in the factory.
The strings are silky smooth to the touch, slides both up and down the fretboard are easy on your fingers and most important, easy on the fretboard.
They are a pleasure to play on, they suit any kind of style in my opinion.
Both slapping and fingerstyle are no problem.
The sound is quite thumpy and well defined. They are clear in their voicing, mellow tone. They are not as warm as a round wound string (round wound strings have more "Mawwww" to them.
One word of warning with these strings, they are quite thick and they are not taperwound. Remeber to check your basses manual to see if they can fit in to the basses bridge. The "B" string fit my basses bridge with some preasure.
Remeber to intonate your bass if you change gauges and brands.
My bass didn't need any truss rod adjustments when I changed from the stock strings to the Daddario ECB81-5 Chromes. The intonation changed so I had to intonate the bass, easy setup.
