My dad's passion was flying. He owned a Piper Tri-pacer back when I was young. He had a heart attack and couldn't pass the physical to continue flying. When I turned 16, he offered to pay for all of my flight school just so he could get back in the air. I had no interest...(big mistake).
My brother was a pilot and since out of the military has not flown because of the cost. Fuel cost is outrageous. I have a friend that just sold his float plane because he moved away from the lake. He always complained about the cost of flying.
This would be more for mid to high HDCP golfers, and players who struggle with ball height. Some players do better with long irons or driving irons, especially if they have high clubhead speed.
Final test: do hybrid and iron side-by-side and see which works best.
Also, Michael is talking about traditional hybrids, not iron replacement hybrids (matched to an iron set). Revisit our 2016 thread for details:
