Ping Pioneer cart bag - I'm partial to Ping bags since I've used a Hoofer for carrying since I started playing golf 20+ years ago. Don't love how the carry bag tends to twist strapped into my push cart, so decided to try out a cart bag for days when I use the push cart.
To add onto what @Vinsk said about a pre-shot routine; at the range, many people don't think about a specific target when in the moment of swinging. Bring that mindset to the course. Prior to the shot, you can think about the club selection and aim. But once over the ball, nothing other than executing the shot matters. It's just you, the ball and the swing, just like being at the range. There are no obstacles, trees, bunkers, everything. Get rid of all "noise." Train your mind on the course to forget you are on the course, when you are hitting a shot. You say that on the range, you can hit all the shots, so bring that confidence and tell yourself you've hit the shot before and you can do it again! Let Will Smith whisper in your ear about the empty field.
The toilet paper of golf.
I have A Sun Mountain, and it's lighter than the Clicgear. Can you tell the weight difference when pushing? Also, it seems that Clicgear seems to be the pushcart of choice, what makes it better than the SM?
