If your asking which one, it would seem that you want the SS. Financially I don't know if the SS is good for you. BUT, if you don't get the SS, do you see yourself at any point saying "Dammit, I should have gotten the SS"? If that is something that could happen, I would get the SS, or wait until you can get the SS. Personally I love the LS. Great power at a great price and you can slowly add go fast goodies as your budget allows. 100 shot of NOS and your running with the SS's or faster. Right Rod1?
