QAV,
I feel the same way. I use the Gemfan Master Series props for all of my birds and my daily flying. They perform well, they're really stable and they're extremely durable. I know how they're going to react and they give me a great baseline, particularly with new birds. I also have a few other props on hand, mostly the Cyclones. They have a bit more pep and sharpness to them. When I really want to mess around I'll swap the Gemfan's for the Cyclones.
