I'm not pretending spin isn't valuable on approaches, but it is hardly "once a year maintenance" for golfers whose day job is NOT 10 hours a day hitting golf balls...
Hardly any components sold by reputable suppliers are of low quality: it is a matter of picking which ones you want. But you do not need to pay for the endorsements and brand names to GET quality.
One of the major golf club mfrs I understand remarked how they had to buy other golf companies to make a profit since their club sales barely broke even: Callaway, I think it was... Endorsements, etc. I didn't pay Callaway prices by a long shot for clubs that because they fit me, are much better for me. I would have to START with Callaway pricing and THEN get them fitted.
My guy in Daytona Beach has been fitting and club repairs etc. - a full service shop - for 25 years; he tells me half of his business is fixing OEM clubs of every description in two different ways: to clean them up so that their progressive lofts ARE what they are supposed to be (plus or minus 2 degrees means sometimes that a 5 iron will be weaker than the 6 in the same set...), and plus or minus 4 gms means sometimes that the 5 iron head weighs more than the 6. AND the lengths, lies, etc. are not controlled carefully. AND FINALLY he has to put in new shafts so often simply because the OEM shafts are not suitable for the golfer who bought "those quality brand name clubs."
And then spines them, swingweights them, fixes the lie angles, etc. Why bother: just get quality components and save all that money AND get properly fitted.
Tom Wishon's materials/advice/counsel is an absolute must for anyone half serious about his golf!
