With my handicap I am not probably the best one to give advice so I will give my opinion.
Sounds to me that your head is getting in the way. The day that you played so well in the
wind is because you may have had the thought "hey the wind is blowing like a hurricane so my
score is probably not going to be that good anyways and you just went out an played with no thoughts
on how you score" The reason that I say this is because I know for me my head is my biggest enemy
and this year I have made a dedication not to think about my score or swing and just go out and
play the GAME. So far it is working I have played twice this year and been in the mid 80's each time.
Just a thought so enjoy and "May your putts always role true"
