I want to buy DR strings. i play slap. Are they best possible strings for slap does anyone know? What is better Sunbams or Lo-riders? I know that Sunbams are Nickel Plated Round Core and Lo-riders are Stainless Steel Hex Core strings. On DR page (http://www.drstrings.com/LoRider1.htm) they say that Lo-riders are for slap, pop and tapping. But many people here on Talkbass said that Sunbeams are the best, but what is better for slap steel or nickel? One more thing is it ok to buy Sansamp Programmable bass di driver as a preamp-for slap bass?
