Don't have the Siege, but do have the Sonar Titan Type III and the Mastery Titan floater lines, both textured. Both lines are far superior to anything I've seen from Rio in the same general shooting head line classes. The texturing doesn't double as a meat slicer like the Sharkskin lines, and are less noisy. I think SA finally has it really going on with these shooting lines, and I do plan to get a faster sinking Sonar Titan to replace my OBS S6 line as it's starting to look a little sleazy. For close in work I'd bet these Siege lines would work great.
