Most of what is out there in the way of full lines, that is with integrated running line, is going to be either full floating, full sinking (of various sink rates) or floating line w/several sink tips. There are numerous running lines available having different characteristics. There are also many heads available, with a myriad of tapers, also ranging from floating to various rates of sinking. Then there are tips, both floating and sinking, and poly leaders. All of this makes for so many possible variations that it would be impractical from a marketing stand point to assemble a package system.
