There are a few things to take into consideration here.
First, there will always be some inconsistencies in the game. You can always expect that. Personally I like the little hiccups here and there. Keeps me on my toes.
Distance into the wind. What balls were/are you using? It can take a while to get used to the distance of different balls.
As for the chip shot you speak of, was the ball in the rough? Spin will not work coming out of the rough.
Was the shot down hill? What green speed where you playing?
This isn't a " this or that " answer. It's what the game demands.
Being a member of the Pinhunters I'm quite sure you can find all the help you'll ever need there.
