The shift is their spin frame. The RF-01 in its 300 variant is more power-friendly, and the 320 is more control-oriented. String choice has a considerable influence on spin. The slightly larger head of the Shift allows for a slightly more open string pattern than the RF-01 but both rackets are good at spin production.

Differences: RF01 vs Shift ?? For topspin
Two very different racquets. Shift obviously has more easy spin
