My brother just purchased a 120 toc edition....... it is supposed to be a higher performance engine used by the original ToC Pilots back in the good old days when Bill Bennet wass alive...... the motor supposedlyt is still not broken in yet.... what prop would be the right size....27x10 28x10? the original owner said it used a 30x10...but i feel its too big.... any first hand users with experience?

how would it compare to DLE111 or a 3w110
