Once you get a few Pro or Elite packs, hopefully you'll have enough power-boosting gear to really boost his power up. During Golfer Setup, you can click LS to see the actual stat values - I got this achievement handily at 290 power.
As for a good hole, Rocky Ridge hole 3 has an open and straight fairway which drops 50 feet from the easy tees. Best way to get to it is Free Play > Rocky Ridge > Par 5s > Amateur Difficulty.
