The Special and the SD-73 Classic, in my opinion, get about the same length, depending on surface prep. They go about it, though, in different ways -- the Special gets going because of its lower RG core and aggresive cover, the SD-73 Classic gets going because of its incredibly high flare potential. Off the spot, the SD-73 Classic is going to be more aggresive in turning the corner, and also cover 3-4 more boards than the Special. The overall hook potential for the SD-73 Classic is higher as a result. In no way, of course, does this knock the Special. You don't always need the most.
For your low rev rate and high axis rotation, either one could be a great choice. Personally, the Classic is in my bag. I like the extra flare -- it can give me some miss room to the right, which is often what I need to get that extra strike, and it is also less affected by carrydown as a result of its high flare potential.
