Hi Roger,

The numbers on your prop sound consistant with my other numbers. My Taurus 2.6 turned a Zinger Pro 20X10 at 7350 when new.

>>So it does come down to performance and price. ZDZ wins hands down on this factor.

Did you mean performance vs. price? If so, I would have to agree....but not performance and price. To me the extra performance can be worth the extra money depending on the application. On a H9 Taylorcraft it wouldn't make any difference, but on a AW 29% Edge, I would pay the extra money for the power alone, but another big factor you didn't mention is smoothness, and from my subjective analysis, the Taurus is the smoothest of any of the small singles.
