RPM team to me honestly seems like the better option. Ive used both, and Blast seems like a stiffer more "baseline grinder" type of string with more emphasis on spin than anything else. RPM Team on the other hand seemed softer, and could do more things as i felt it was easier to flatten out shots, but also gave a lot of spin, and feel when needed. I think RPM team is the all around string, at least it was for me
