When I’m on the course, I normally take Lipton green tea, but I’ll drink the water from our water coolers, which is normally ice cold. I generally don’t drink water unless it’s cold. Sometimes, at the turn, I’ll get a Dr. Pepper and sip on that throughout the back nine.
Here’s something I’ve tried that I like: take a 20oz water bottle that 3/4 full, then get a Sprite and fill the other 1/4.
A few minutes on google came up with 1975 for a very similar model just cosmetically different in the script and so forth, so that would lead me to believe that the ones you have are only a season or so off plus or minus. The exact ones were on Ebay with the aluminum shafts for 275 bucks. I think its a nice looking club, I like that old school look. I am curious as to what an aluminum shafted club feels like to hit.
