I've got the Cobra F7 3/4 Fairway in my bag alongside the Cobra F7 Driver.
I agree the 'baffler' rails on the fairway are good.
if you like the F7 versions, you will love the F9. I tried a F7 driver, but we didn't click. Then I tried a second hand F8 with a stiff flex shaft , which I liked more. I bribed myself to go back to work for 3 weeks out of retirement by selling off my F7 single length irons, my F8 driver and buying "new" F9 single length irons, a F9 driver and F9 3-4 wood.
At first I thought I had made a mistake with the driver shaft flex between the stiff F8 and regular F7; but now it is working very well. The F9 3-4 wood is a vast improvement over the F7 version with addiitonal distance and control. I kept the F7 hybrids 16-19/ 22-25 degrees as I was no better with the F9 versions.
