There are not a lot of things that I'm sure of with regard to golf. The one thing I AM sure of is the Cobra F7 hybrid is the best Hybrid that Cobra has ever produced. Better than the Speedzone, better than the F9 hybrid, WAY WAY WAY better than the F8 (The F8 was a giant step backward for Cobra Hybrids).
That said, the Speedzone and the F9 are fine hybrids. But the f7 was simply better. Better shaft options and it was the last hybrid Cobra produced with the "My-Fly" technology. Additionally, it was not "Snap-hooky" like some many hybrids of a few years ago were. The baffler technology was at its peak with the F7 as well.
You don't have to take my word for it. Go out and try to buy a used Cobra F7 Hybrid... Holy cow, there aren't any available, There are plenty of F6 hybrids (even some non-used ones), There are tons of used F8 hybrids (Again, big step backward IMO). There are F9's and even used Speedzone hybrids already available. Good luck finding an F7 (unless you are a lefty). Those of us who have F7 hybrids are not selling them. You can pry mine from my cold dead hands.
Guess this comes as no shock to anyone, I'm coming to this late, thought it would have been posted here already.
November's Masters golf tournament at Augusta National to be held without guests or spectators

So I have played / owned the ones you listed. All fine clubs. The Ping was my choice due to ball flight and accuracy for me vs the Callaways. The Ping was not the longest but I desired good consistent carry distance and could actually hit into greens without excessive roll out. Obviously everyone is different and many can hit others into greens fine, I just could not with the Callaways (but Ioved the total distance they yielded). But recently I hit a Cobra hybrid and now I am thinking about trying the listed in the link below. Good luck on your search.
