A funny thing happened to me. Like most, I started with straight bars. Then I discovered that road bars are like straight bars with two additional hand positions. Now, the more I ride, the more I'm appreciating road bars. The lower the position that I am on the bars, the less weight on my butt. While I can't do it forever, I've found that the drops actually give the best weight distribution with virtually no butt discomfort. I realize that this is not a great secret, just a personal discovery.
