Anybody use Dutchman Motorsports axles?

I hear mixed answers on having axles resplined. I am running a 4-link and narrowing a 9". I have a set of 31 spline axles that I could have narrowed and resplined and save some money. The car these are going in my street car and will run down the strip every once in a while. The car will not see more than 450 hp eventually. I am installing a detroit locker and 3.89 gears. What do you think? Strong enough with the resplined axles?
