I don't own Zoars in this size range. Only APC, Bolly, Mejzlik and Vess. I posted rpm data in the Tach forum for the MT35 and DLE30 to keep this thread pure. I won't mention these other engines in this thread again. If you would like to ask questions or make comments go to those threads or pm me.

The Syssa spins the Vess 18x6 so well I don't see the need to run the Vess 19A, you won't get any gains in power, maybe reduced noise?
