Your second question, 5W or hybrid? A couple of things to consider...
- How far do you hit the ball? If you're reaching for more distance, a 5W would go farther than a typical 3H due to longer shaft length and somewhat stronger loft. Also, 5W has more bulge (curved surface to the face) which creates gear effect. In fairway woods, the gear effect spins both toe hits and heel hits back towards the center of your target line. This can be helpful if you're not the world's best ball-striker.
- Need control? A hybrid has a shorter shaft, so might be easier to control. If distance not a problem, hybrid might work better. But, some people have trouble hitting hybrids.
- Can you handle 2H? (compares in distance better to 5W). Average golfers sometimes find the stronger lofted hybrids (17-18*) difficult to hit - especially out of the rough. For this reason, recent Adams and Callaway hybrid lines only offer the 2H in the Pro or Tour segment. (Three different demo day club reps cautioned against average golfers using 2H)
And, compare the two in how they hit. Go with what works better for your game.
NOTE: June Golf Digest had an article "Secret Weapon" about recent technology upgrades to make FWs more user-friendly. I predict that in 2012 more club manufacturers will push the 5W and 7W as alternatives to hybrids.
