What did you mean by this bookworm? That in these airplanes that you describe C/L max is the best glide speed, C/L max is Vx, or both like FE hoppy said?
I misread it as L/D max, which is equivalent to best angle of glide in all aircraft, and best angle of climb in a constant thrust aircraft (ideal jet).
C/L max, by which I now presume was meant maximum lift coefficient (CLmax), has nothing to do with best angles or rates of climb, unless the stall is limiting angle of climb, which is unusual in a prop and even more unusual in a jet.
