Ciao!
For all C4 blades the stiffness is:
- 25 soft
- 30 medium
- 40 hard
80 is not the blade's hardnesses but just the name of longer fins for Apnea.
GHOSTS,to help you, I need to know something more...
a) Where are you from?and where do you usually dive ?
b) How tall are you and what do you weigh?
c) Are you an experienced diver?

e) How deep are you going?
