Need some advice for some new Golf clubs.

I am not sure if this goes in General or sports so I thought I would try it here first. If it should be moved over to sports by all means please move it.

Well I think it is time to replace my old Ben Hogan forged Edge irons. I am thinking about the Taylor Made R7 irons, and I know a guy so I can get a deal on them. I just wish I could order 5-9 irons, as I have Cleveland 52, 56, and 60 degree wedges. I am also finally thinking about changing over my 3 and 4 irons to hybrids. The two I am looking at are the Callaway Diablo, and the Taylor Made Burner. Has anyone hit hem both, and can tell me the difference.
