The diameter of flatbars is also slightly less which makes it even less comfy if you have big hands, but of course to make it more comfortable you can do a double wrap or so. Still not worth the trouble imo
I've only done it with the Brooks tape with cushioning underneath for the looks and then on a beater just to keep the cost down. I did make the overlap much closer so to give more cush.
No. They're wrong.
Regular bar tape has downsides, but being uncomfortable isn't one of them.
Cons:
*(grip position means less moving about and resting than with drops so you put more wear in a single spot than it's designed for)
