Thanks for clarifying!Misspoke above -The simple equation for ROC is (T*V - D*V)/W

So, in yor example, the lighter of the two FW 190s assuming all else equal, will have a better rate of climb.

Where the W/L comes into play for your example is when parasite drag of the two are equal, but the wing area is different - is that for the same veocity the larger wing/smaller CL in this comparison - has less Induced drag, which influences the above equation.

The devil in the details is that for same airfoil and wing construction, the profile/parasite drag should be lower for the smaller wing area version perhaps offsetting higher Induced drag.
