propeller help for speed - TFL 1106 Pursuit

Hello everyone,
I have TFL 1106 Pursuit, I need help choosing a final speed propeller (70 miles or more)

See my settings and speeds:
SSS 4074 22000kv + ESC Seaking V3 180A (Timing 0°)
6S 5200mha 60C
OSE propeller shaft

propeller: octura x445 = 92 Km
propeller: octura x447 = 96 Km
propeller: ABC 1715: 83 Km

Could you help me in a propeller that I can reach 70mph?
