Well, have a nice laugh when people express an opinion you don't agree with. In my opinion (as I stated), they aren't made for long distance riding and my personal experience - and the fact that I personally don't know anyone who does long distance cycling with straight bars - formed my opinion.

I don't laugh at your opinion or experience. I'm sure it's true for you and others, and worth it for the OP to explore how to make those flat bars work for him with additional accessories. But it's interesting that the bars themselves aren't working for him, but adding on a feature which accomplishes what other bars do by design will probably help a lot.

I don't think I was saying the bars couldn't be made to work by adding accessories. I think I was saying that in my opinion they aren't really designed for long distance cycling.

I don't disagree at all that you might be able to make a bar work by adding bar ends -no big deal, I've even done it. You can also add another position by adding clip on drops to flat bars. Both work well, but, in my opinion are workarounds for bars that simply aren't designed for the purpose. Trekking bars and drop bars in a good comfortable position on the bike are made for the purpose.
