First thing you do is take away the idiotic equipment specs that Champs are able to use.
In other words when you hit Champion Tier.
1) Your clubs lose all forgiveness.
2) You lose the ability to use the chip / pitch grid view on the green. The aiming line is gone when putting, you just see the arrowhead.
3) Champs use a special ball which is neutral, as in 3.0 3.0 3.0 3.0 / 3.5 2.5 3.0 3.0 That's it. The extra spin ball loses a bit of distance as it should. As a bonus for reaching Champ these balls have 3.0 wear limit. You can't buy any other ball - and they come in Nike green as well because they do still market them.
4) The ding line should vanish as soon as you let go of the mouse button on all shots, so you spot it, watch and then draw your club back, release and the line disappears and it's up to you to 'focus' and try and hit the perfect ball strike. Still chimes if you hit it.
Come on man, you're Champs after all! If you don't want to have to play harder, concentrate then stay a TL, simple.
