Boyd,
The speed that gives you the best rate of climb changes because the prop's
efficiency curve moves its peak efficiency to a higher or lower speed. That
means that the maximum excess power is at a different speed than it was
previously. Might not be much, but it's there if you look for it.
You'll also find that the best L/D speed changes with prop pitch and whether
the prop is turning or not. Again, it might not be much, but it's there.

-------------------
if you change props with different efficiencies you will change the climb
rate
but not the best climb speed. the best lift to drag speed will remain
the
same wether going uphill with power or downhill in glide.
