If you are a bassist (and if you're reading this, you should be), you owe it to yourself to try a set of LaBella strings, if you haven't yet done so. You can get get virtually any formula/construction/gauge/scale length for your style of playing and every series delivers EXACTLY what LaBella promises. I'm a huge fan of the Deep Talkin' Roundwounds, but I also use the DTB Flats, HRS (now called "Stainless Steel Series"), Nickels (formerly "Slappers") and Super Steps, depending on the instrument and the type of gig. They offer the widest variety of gauges in their sets, and you can "custom gauge" your own set through BSO or JS. A shout out to their Customer Service folks for OUTSTANDING support. Buy a set NOW or check them out at NAMM! I'll be glad to share my experience and results if you're interested!
