When dealing with air resistance, differences in shape have the potential to cause more of an impact on speed than differences in weight.

Don't you see the game that guy is playing with you?
Apparently you have not seen this, so here it is again, containing all the variables you are talking about
:
Vt = sqrt((2 * m * g) / (rho * A * Cd))
where
Vt = terminal velocity,
m = mass of the falling object,
g = acceleration due to gravity,
Cd = drag coefficient,
rho = density of the fluid through which the object is falling
A = projected area of the object.
Do you see that term "m * g"?
That is called w_e_i_g_h_t.
