On one bike, I run Yamaha teardrop mirrors. They came on the bike, and I don't know if they are OE or aftermarket (all look the same). They are probably just a bit smaller in total size (rounding off the Honda square corners), but about the same in function. What I really like about them is the arms are turned around crooked, and go straight up, and not out. They work well for me as I am not tall, but their position is high enough, I am not looking at part of my shoulder.
The problem with most aftermarket mirrors, besides all the goofy shaped and tiny ones (which are all blow and no show), is that 1) adjustment is often very limited, and 2) they won't stay put. Using Harley or other mirrors that require metric adapters at the mount, always and forever swing loose, and cranking on the wrench eventually strips out aluminum threads.
I had several sets of Kuryakyn large magnum mirrors, on both short and long arms (with convex, not flat glass), and they are beautiful mirrors, but the metric adapters would never hold for long, and it was a real problem getting them set exactly where I needed them to see behind me (adjustment is very limited, so you end up having to change how they mount to the handlbar, not just move the mirror on it's pivot). Threads started stripping and I used plumbers tape for awhile, and now they all sit in my parts bin, and I put the OEs back on. I do not like how OEs look (plane jane) but I sure like how they work. Note my Yamaha mirrors always work too, but the arms are turned around, so they go straight up from the bar.
Most taller guys need
taller mirrors, not wider ones. This is an arm length issue, not a mirror issue, except most all OE mirrors, it's a complete unit. You cannot stick longer arms on, and many with a bend make them too wide, not taller. Wider may let you see around yourself, but you are looking too far away from the road to use them. Taller lets you see over your shoulder, not through it, but your eyes don't have to move clear out to the side to look at them. And BTW, if you haven't figured this out, taller handlebar risers helps with this issue.
I've always found it instructive that of the many beautifully tricked out Valks you can find at Inzane and elsewhere, most guys are still running the OE mirrors. It's not because they look good, it's because they work good. IMHO
And you know the old story; returning parts you installed with even the slightest tool marks are not accepted, yet how can you know if something will work for you without bolting them up and riding around with them a bit?
Like these:

A bit longer arms, I think these are what I have. (mine have this fat rubber gasket, unlike above)
