The V-easy has been a great help. Not suited for anything other than shortish chips but it takes the wrist out of the stroke and gets a great feeling of connectivity. 15 minutes per day, alternating between a few shots with the v-easy and then a few without reallt made a difference. Like you alot of it was between my ears. I had a chipping lesson recently. The pro said "do you think about the technique when you are chucking a ball to your mate?" Of course you don't. You just do it and the brain works out the strength and technique.
If you can get a stroke that is simple and repeats then the brain will do a lot of the feel for you. The more you get hung up on the how, the less you can focus on the do and everything becomes chipping by numbers, stiff, wristy and out of sorts. I'm much better now at trusting my stroke and focussing more on where I want the ball to land and believing I can put it there
