Long 5 is a bit flex blade and carbonado 190 is a bit stiff blade, keeping aside the carbon layer structure. You could relate long 5 with 145. So if you want to really buy, flexy- long 5
Stiff-190.
If you want a HL5, you could just buy innerforce ALC instead. Both blades consist of same ply wood. I think in terms of carbon blade used by pros, the most used are: viscaria, innerforce ZLC and Mizutani ZLC or Innerforce ZLF (LSW)
