The aim for this achievement is to play under par on Burning Sands with all 6 of the characters.
Firstly, you need to progress through career to unlock the 4 additional characters, together with the initial 2 you have unlocked.
With all characters unlocked, I then got the achievement using Free Play, Burning Sands, Par 3 Holes and Amateur.
The key here is that the tees and pins are always in identical places, and the wind is almost always nearly the same.
What you can do, with a bit a patience is play as a character, with Kirby as the caddie. Aim where you think is correct, then use B for shot preview. You can then adjust your aim, but more importantly, you know where to aim roughly next time as well. Play the rest of the holes (to get to know the layout), then play again, using Kirby on the next Par 3, and so on. After 4 retries, you then know roughly where to aim every time.
For my next try, I switched caddie to Astrid, so I could use putt preview to birdie one hole and then try to par the rest.
I found using different characters, who hit the ball different distances didn't matter - more important was where you aimed the cursor for the shot.
To help I aimed as follows;
First Par 3 - (15mph head wind right to left) - back middle of the green, with maximum backspin on the ball
Second Par 3 - (20mph back wind) - down 2 clubs and maximum backspin
Third Par 3 - (10 mph left/right wind?) - up one club and aim just into the lava by the bridge, little bit of topspin
Forth Par 3 - (15mph back wind?) - maximum right to left spin (draw spin) aim for middle of the green
This set up gave me about 12ft birdie putts for the first 2 holes and on/around the green for the next two. As you only need to finish 1 under, you only need 1 birdie using Astrid.
Please note this is a guide only, and depending on your perks/clubs this may differ slightly. The Kirby route is the best way to know for you - my guide on shot location is just if you want to speed matters up.
For perks I was using "lucky drop", "10% less wind" and "25% slower swing speed".
Remember who you use - I don't think there is any tracking method and the new XBox One progress didn't seem to track me on this either. I did it in one sitting in about 90 mins. When you know your locations to hit it, future characters are quicker.
PM me if you want to use my caddie to help! Good luck!!
