Kuzma 4Points and Lyra carts

Agree with @artemus that there might be small differences but the 9" will be easier to setup than either the 11" or 14". Both longer arms will require VERY precise alignment, not saying the 9 doesn't just the 9" will be easier. 

I might disagree about longer being better. Theoretically, yes it should. But others in the know like Michael Fremer have said the differences are not that great & that a well setup 9"arm will perform as good as a well setup 12" arm  There will be differences but like most everything it is a trade off. Maybe you will like the trade. Maybe not

Either way, I hope you both well with the Kuzma. It is on my radar as well. Then I listen to my TT and ask...why? Hard decisions

FWIW "I think" the 11 will outperform the 9 and I hope the 14 will outperform the 11 because my 4 point 14 will be here next week and the difference in $$ is substantial. Everything you read says longer is better

Currently have a DP6 and a DP8 both with 12 " blue dot arm wands. so I'll report back whether the 14 outperforms the Morch.
