That's only my opinion.
If you're happy with what you are are using though, keep going with it.
Interesting!! My only issue is there is a slight sluggishness on low end. I've contemplated modifying my throttle curve to compensate. Example is bottom of an outside loop maneuver I notice the need for more aggressive than normal throttle is needed to begin the upward half of the loop. I hate to think of a faster flying plane but I'll give it a try as I have a 18.1 x 10 handy.
Thanks!!
