Got to try the Bullnose props from HQ.
My thoughts are:
So much stiffer, much more responsive.
Quieter.
Well balanced.
Better yaw response
Great power.
Easier tuning.
Down side is being stiffer, they are really brittle. I had a slight tip over on a landing, and broke a prop.
Only had one set, so need to order more

For those looking for performance, these are awesome.
For those learning, not a good option, as you'll break a LOT of props.
