These strings are great, really, really great. They are slick to the touch and have just the right amount of tension on my 35" 6 string bass. I replaced my previous round wounds with these flats, as the previous strings were just too bright for my taste. These have that nice low 'thump' and a fantastic tone that is harmonically rich throughout the full range. I use these with my MTD USA.
I have used these strings now for a fair time, and have found that they last really well. You could probably get away with never changing them if you took care of them and wiped them down. I still make good use of slapping and popping occasionally too, and the EQ can make up for the 'less bright' tone of these compared to rounds to my tastes.
