Have recently bought a golf bag with dividers that dont cover the entire lenght of the clubs. Im afraid that they will be damaged on the flight by handling.Which is the best bag to buy to make sure that the clubs are safe?

I was wondering if anybody knew if there is any way to get good golf irons (titleist, mizuno, callaway) for cheap.

Im looking on the internet and I see all this stuff about Hybrid golf Clubs.

What are they and what is there use?
