Suppose I put this prop on my Cessna 150. It only weighs 9.5 pounds,
as compared to the Sensenich weight of 24 pounds. So I save 14.5 #.

But it will make a largish change in your CG. The fuel and passenger load
for a 150 are both near the CG, so you might end up putting a few pounds of
ballast in the tail to stay within the CG envelope. That would cost you some of
the initial weight advantage.

Can anyone guess how this would effect my performance? How much
better climb and how much better cruise?

Nobody can answer that question until you specify a pitch. Any given fixed
pitch prop will be optimized for climb (at the expense of cruise speed) or
cruise (at the expense of takeoff and climb performance) or somewhere in
between.
