David, I am not qualified to offer official advise. However, I love my 5-wood (metal as you call it). I have had a few that I couldn't hit well, but the one that fits my set (Warrior Custom Golf) is perfect. Rather than buying a brand name off the shelf, I would suggest getting the proper fit from a pro. They will check out your swing, the swing speed, and put that together will all your measurements to come up with a proper fitting club. I know you probably like your R7, so do I. But, my other clubs come from my set that I had fitted for me. I would suggest at least taking your 5-wood to Nevada Bob's or some similar facility where they can measure you, check your swing using an electronic indicator, and letting you hit some clubs. This Forum has a very good T2G Pro that will probably give you some better advise, but I find that there is no substitute for confidence. I play with clubs that I have confidence. I am getting older, so my swing speed may slow some soon. When that happens, and my shots are consistantly off target, I will get another fitting. Good luck, Scoops!
