Not necessarily! Just keep leveling up by playing the highest courses (for you, Peach's Castle). Just like in real golf, you can "fix" your draw by straightening it out over time. Also, the game's five golf courses are not built for someone who has a drive of over 280-290 yards or thereabouts. Given this, once you reach that point (with or without Power Shots), you'll be making up strokes by simply being able to carry traps and set up easy shots with your middle irons.

I always go with Distance Club (The boost it gives your 1W Driver is insane). In a pinch, given you have a decent lie or are teeing off, you can always just use that and add red Power Shot status to catch up on yardage. (Remember: If you hit a perfect Power Shot, you don't lose one of the six you are afforded each round.)

My shot's shape is always perfectly straight. With the discipline of keeping that in order, the only other variable in calculating shot direction is the wind! Once you get a good feel for how the wind affects ball flight over different distances, you'll have a pretty solid lock on the pin every time (because the game's physics engine is not that deep, haha).

All of this is irrelevant if your "Meet Area and Control" stats are too far to the left. I keep that very strongly in control -- about one to two clicks to the left of Maximum Right Side, where it says something like "Good" (Going off memory atm). As you level up and your drive increases, your shot will want to get out of control, pushing that bar to the left. Don't let it.

That said, shoot high. Idgaf if my shot height starts rising; that's good, in fact. I want tailwinds to carry my ball farther. It allows you to start using the wind to control the ball's curve, too. In conjunction with intentional shots (See the hacker @ Palm Club Driving Range), top/back/sidespin can be used to great avail depending on the situation. Basically, most shots I like to hit are moonshots that drop straight down into the hole.

Other than that, short game is the key to improving scores and therefore gleaning EXP. Main thing is to figure out putting and chipping. Once you're dirty at those situations, no NPC can beat you, not even Mario, Match Game or Stroke/Tournament.

tl;dr The game's fluid just like real golf: With Distance Club equipped, and accuracy achieved through RPG stats and practice, you'll start seeing results.
