For somebody with a 20.1 index that may translate to a 25HC? This is too much golf hole. Whether you try to play to the green in 2 or 3 shots will likely result in a six....this is a tough call.
My only advice is to play shorter tees!
For this hole, it's just two long straight shots. A longer hitter can hit a drive through the right side into safety and then it's a decent long and straightforward Par 4 leaving a mid to longish iron approach. Shorter hitter will need to place it better along the right side (that's 'skill' to me) to get that similar shot (long iron to hybrid approach).
I'd just suggest he balances the risk of going for it in 2, vs just playing it safe like a short par 5 and hoping for an easy short approach.....
4 or 5 is a good score here.
That area to the right seems pretty open if you hit driver, which I would because I hit a draw mostly but even if it stays straight or moves right that's pretty wide open for a miss. Not sure if you mentioned what your miss is with the driver. But with the elevated tee your normal drives should put you passed the trouble on the right. From there if you are in the rough I'd lay up to whatever distance you are most comfortable with wedge wise and go for 2 putt bogey or 1 putt par save. If you're in the fairway I'd go for the green favoring a club that will leave you short of the green as opposed to long.
