I use my SW (56) 80% of the time. If I have to get it up and over a bunker or if I'm really short sided, I'll try a flop shot with my 60. I feel very confident I can put the 56 within 3-4 feet of the pin which is why it is my goto club.
And the more your opponents know this, the more they're going to get under your skin on purpose and completely within the Rules.
Lose the hair trigger/thin skin/whatever you want to call it.
It's still a competitive sport, and if making an innocuous comment that isn't anywhere close to poor etiquette gives them an advantage, one could make an argument that they're being unwise to not do it.
These aren't close to "gamesmanship" which, while also often fine under the Rules, is closer toward "scummy" behavior.
One could also make the case that you were looking for an excuse, because "man that’s a tough shot there, glad I don’t have to hit it" isn’t even bad etiquette. It's not gamesmanship. It's incredibly tame, almost supportive.
Worrying about your swing mid round usually doesnt work out well. Especially if youre in a match or tournament. When I played a ton I would work on my swing/swing thoughts on the course during the week and on the weekend rounds or tournament I would just play with what Ive got. If you practice enough your swing will evolve for the better.
If I ever get to the point where everything is automatic and I don't have to actively think about it I'm sure emotion would help, but for me the madder I get the harder it is to focus on my swing techniques..
