Sort of a two-part question.
First, is there one? (A relationship between how fast you swing back translating into swinging forward harder).
Obviously, at a certain level, a backswing speed is somewhat required. I had a bad front 9 this past Saturday, and headed to the range. I was doing drills at a very slow speed working on squaring up my clubface (my fade was starting right of my target line, which is a big problem). I noticed that I could explode forward even with a very slow backswing, and I was getting really good results swinging back what I felt like was very, very slow slow. Watching Ryan Moore in contention this weekend as well - very slow backswing, smashed th ball a really long way. Strangely, the club that saw the most improvement from a deliberately slow backswing was my driver. While I started the drill (the "clubface control" drill in a few Iacas videos) going slowly, I found that a very slow backswing could still hit my irons the same distance as my "usual" backswing (8 iron about 155).
You read that there is the "tour tempo" theory - that all tour pros have a 3 to 1 ratio from backswing speed to downswing speed. Is this true? This doesn't seem right to me, but seems to be accepted wisdom.
I could swing back fairly slow and still hit my 8 to the 150 and it felt like a I had a ton more control. Increasing my backswing speed didn't do much, on its own, to increase my downswing speed. However, if th 3 to 1 theory is correct, a slower backswing would mean a slower downswing, all else being equal, which doesn't seem to be the case.
Does 5SK teach anything about the speed of the backswing? Is there any sort of relationship there to downswing speed, or is it a comfort issue with no "right" answer?
Second, how often do the really "good" players here dial down a club to hit an approach into a green?
I was watching "Golf's Greatest Rounds" and they had the 2013 British. They showed a "swing vision" sequence that had the clubhead speed for Lee Westwood hitting a 9 iron. It was about 80 mph, and the shot was relatively short. Now, this is a links course, but the practice range time got me thinking - if I slow my PW swing down, I can hit a ball straight about 110 with some roll out. Usually, when I play, I'm hitting the iron that goes the distance to my target - I'm not slowing down and hitting a "longer" club. However, Westwood clearly did there, and I then saw McDowell hit a 9 from like 95 yards in another tournament (it bounced in). Is this a common thing among really good players (haivng "slower" shots that roll out with different clubs)? Is this something that should be worked on on the range?
I'm thinking about how to get my iron play more consistent and it seems like slowing down could be a good way.
