I cant speak for the Pro Solider, but I can say how awesome the Spartan Blades guys are to deal with. I had issues with my Spartan Blades Ares, and they had better customer service than any company I have ever dealt with. All my issues were dealt with asap and I even got a hand written letter explaining what happened and apologizing for the delay. You gotta respect that type of customer service and their knives are second to none in quality. I have owned and sold my only C.R. but I kept my S.B. if that means anything.
