I can't give any advice because I also hit the ball pretty low. Just wanted to make some observations. My brother is my usual playing partner and he hits pretty much everything super high while I hit low line drives for the most part.
If there is a crosswind, then our distances are pretty much the same, give or take about 5 yards, but mine will typically be more accurate since it's not influenced by the wind as much. If there's a tailwind, then he'll be quite a bit farther than me. If there's a headwind, then I'll be quite a bit farther than him usually.
When it comes to approach shots, he can hold the green better than me since his ball isn't going to roll forever, but I tend to get away with mishits a little more, as long as it's not a complete shank, than him since I can land mind short and still roll it fairly close.
So even for those of us that can't seem to hit a high shot, there are some advantages to the low shots that want to roll forever.
I did manage to hit a beautiful high approach shot the other day with my 8i. I got it high into the wind and it went nicely over the pond and landed about 5 feet from the pin and rolled right about 2 feet. I just wish I could do shots like that more often, but have to take advantage of what I do best, which is hit the low line drives.
