You want to be flexible on the course. To have more than one kind of shot around the green is very important for learning to get "up and down". SW is the most flexible club in your bag (once learned). Many golfers are afraid of SW (and they should be if they throw/release the club head of SW around the green (Skulled or Chunked in a hear beat). Once they learn to maintain the setup shape and rotate, WOW dozens of creative shots are available! You start to "lick your chops" around the green thinking you can "make it" from anywhere off the green.
I will say.. if you like a club, and you know how it performs, use it !! When you're playing, on the course, you use/do what ever you believe will give you the best chance to get the job done. On the course you're playing for "score" and following your " routine" *. Never try a "new" shot on the course when things really matter or under pressure. It is critical to protect your confidence in golf, so always play the shot you know. * Like "what you eat you are"... "what you practice/repeat is what you get". Let's say you go out on the course to practice, then hit a shot you don't like... so you throw down another ball and try again and still didn't like it .... so you're now a little frustrated and rush to throw down a 3rd ball and you're worried there is something wrong you can't fix... so you hit the 3rd (without your routine) to try to get your confidence back, and end up hitting the 3rd shot worse than the first 2. Wow, now you've really gone backwards with the confidence. What was just "programmed"? Two days later you're with your friends (on the course for the real game), ... get to the same shot you missed 3 times... what do you suppose is going to happen? Moral: Practice at the range... Find time to also practice your "routine" at the range ... AND ...when on the course, take every shot using your routine (or don't take it). Better yet... if you miss a shot on the course, don't take a second shot trying to fix it (and your confidence)... think about it some ... then do some well though out practice at the range, after the round, when the "missed shot" from the course isn't fresh in your mind.
