Buying new 3 fairway wood

I am changing from a reg shaft to senior shaft on my Driver and 3 fairway wood.  I am 72 years old with back issues.  My swing speed is a dismal 65-70 mph. In purchasing a new 3 wood with senior shaft would you suggest 15 or 17 degree loft (distance is my big concern)

The stock answer is to get to a Golfsmith or something and try both out to see which you hit better! Besides that, 3 woods increasingly have adjustability. I have a 3 wood I use that goes from 13°-17°, the Nike Covert Tour (2013). Cost $89 through divot daily I think. That way you can adjust as you see fit. Side question: is the 3 wood for teeing or off the ground? If the latter, 5w might even be better.

Maybe Callaway BB V series Heavenwood? 20.5° loft with 3 wood length.

There are so many good fairway woods out there, you really need to go to a golf store or Demo days and give them all a try.  Given your swing speed I'd suggest Callaway XR, Cobra Fly-Z, Adams Tight Lies 2.0, and TM Aeroburner.

I currently own a TaylorMade recently purchase new Adams Speedline F11, steel, draw. I could change the shaft on the Adams to senior or purchase a  2014 Jetspeed Fairway Wood for about 80.00. Kind of a toss up from a dollar point of view.  We do not have a golf store where we live (closest one is about 100 miles) Any thoughts off the top of your heads.

Sorry change that to I currently have an Adams 3 wood and looking at TaylorMade Senior flex

Second this...

I think Callaway made this club for two types of players -- those who had trouble launching fairways but had speed; and

Slower speed players who need more loft for carry but want more distance than a traditional 3 wood -- with the BB V Heavenwood, you get a volume head that is larger than their 5 wood, 20.5 of loft for carry, a 53g shaft, and 43 inches for more speed.

And it's an easy club to hit even with the longer shaft.

For a good price, go to www.callawaygolfpreowned.com, find any coupons, and see if they have a senior shaft.
