thinking about bigger bars

If I were you I'd go with the odyssey boss, cuz odyssey haha

I'm 35 and 6' tall. 9" with a top loader felt far too tall for me. It's all personal preference. But I was the same height 15 years ago when front load stems and 7.5" bars cut down were cool. We're all over thinking it.
My personal opinion is that will be a big change, and you'll either love it or hate it. If you hate it you'll have to spend more money dialling the height in with a new stem, or go back to your old bars and lose money on the resale of the new ones. Try 9" first, see how you get on, then get a higher/lower rise stem from there if you feel you need to. You might even have enough room on your steerer to drop a bit too if you feel the need for it

if youre going to bars id just go with the odyssey because its not too drastic of a height and they make super solid stuff.
