Smaller sail

[jesenko]

My smallest good shape sail is Retro 5.0. What smaller size should I get for 85L board. I am 170lb.

Hucker 4.2 ….you said once it works like 4.5-4.8, so no good…or good ??

Hucker 3.7 ..too small…I think

Revo 4.2 or Revo 4.0 or !@#

Thanks

Ps. What is water temperature in sound.
