IFMAR is the model you want more torque than the EFRA versions
Judging a crank performance by the number of mallory metal inserts on their counterweight is just a nonsense. I could be worried more for other parts of the engine rather than the silly inserts (IMHO).
Don't worry if they have two, one or none... by size and weight a .12 crank could not hold 2 inserts on their counterweight and depending of the pendulum cut, could need one or none just to get the counterbalance needed for the reciprocating mass of the piston and conrod.
