> Just saw one for sale. I assume it's the original Medicus 5 iron until the dual hinged one got invented. Anyone used the single hinge? Do you think it could have merit?
I guess the bottom line is as the man says, "you spend your money, you take your chances." As a tool, it's been around for quite a while, and in fact there are Medicus clubs in both woods and irons. If it would not have had some merit, it would have disappeared. Seems like a lot of amateurs have kept it in business and their R&D dept working.
I had the club when I lived in the north and couldn't play for several months of the year. This helped keep the swing working over the dark days. Now, I personally don't have that problem and I live wherever it's warm, can use driving ranges and don't have to practice in the garage or basement. Not everyone is as lucky so for them, this tool might just be the thing they're looking for. Remember, the average handicap for men is upper 14s, low 16s and according to countless articles, has not dropped much in many decades....despite improvements in balls, clubs, courses, etc. This grouping is looking for anything that gives them an edge and a smoother swing might be what works for them. That probably means most tools, aids, opinions and tops have not changed much over the period either.
