Kuzma 4Points and Lyra carts

I am currently enjoying a Lyra Etna SL on a Morch DP8. I am interested in trying a Kuzma 4Point.  I have heard that many find the Kuzma/Lyra combination to work well.

Does anyone think there would be an advantage to the 4Point 11" over the 4Point 9"?  Specifically with sound quality not VTA tower use. 

Thanks!
