Apiera,</p>

That really surprises me about your findings on the 19X11.  It is by far the most consistent speed propeller I have flown on my CDI.  I had similar results as you when I tried the 18X11WPN.  I just flat out hated it.  I have not flown a 17X13, but with my airplane choice (Black Magic) I have been throroghly impressed with the speed range of the 19X11.  As you stated, it is definitely a matter of choice and flying style.  I have also noticed a much broader speed range that the prop allows.  It allows you to fly very slow and close if needed, but you can also push it out and fly faster if needed.</p>

As you said though, people need to try various props to see if they fit their flying styles and needs.</p>
