Rodie with a gravel bike here. I'm still waiting for my "Aha" moment with the FSA Adventure bars I swapped in for the stock Eroica bars. Both are 46cm but I don't really feel opened up on the top. I've only got 4 rides in, though. I don't find the sweep section on the drops very comfortable. Maybe I have big hands.
If my road bike wasn't in storage, I'd swap in those bars with the flat ergo drop section. I thought those were the most comfortable.
Time will tell, I guess.
