Conclusion
The new Pit Shimizu R1-H seemed to grip better than my used R1 (medium), but I am not sure if it's because that the my used R1 has already lost its grip. The fair comparison would be to use a new set of R1 and R1-H for the test. Note that the R1 and R1-H have thinner inserts than the R3 and R3-S. Next, I plan to test different combo out again using 3-series tires, and then finally, mix and match.
