Welcome to TST.
Although basketball cannot be compared to golf, I have made the switch from right-handed to primarily left-handed play as a point guard.
It took around six months of intensive training to be comfortable with dribbling and shooting with my left hand.
Besides the training, consciously switching to the left hand for my daily tasks like eating helped a lot as well.
Pity about Bryson withdrawing. Hopefully he will be ready for US Open 16 - 19 June and British Open 14 - 17 July. St Andrews will be a good fit for his game. The English golf fans are keen to see Bryson. 22/1 with British bookmakers to win the St Andrews Open.
Brooks Koepka, playing with Lowry and Scott, is 33/1 in UK to win the US PGA. Could he do well?
Worked on feel from recent lesson with 4-iron and PW, hitting balls 1/2 swings. Teacher suggested to alternate between long club and mid/short club when practicing since she observed I overswing with longer club in hand and thought that might help tame it. Used LVP camera to replay swings during practice but video quality was grainy in low light.
