RDS 001 MP is easier to swing, easier to generate spin due to the lower swingweight.
I have seen posters saying the the RDS 002 Tour plays differently compared to the Ti-80 but I disagree. To me, they play quite similarly, similar feel, similar power level. The Ti-80 has a more metallic feel to it than the RDS 002 Tour. Both are solid frames but the metallic feel to the Ti-80 can be annoying to some.
