For fear of looking like 'that guy'... how fast/strong does one need to be to justify wearing (this) aero helmet?
Why did you buy it if you don't want to wear it?
It's to make you faster. If you want to go faster, wear it. If you're overly worried about appearances, you're in the wrong sport. Most people think everyone in lycra looks like an idiot anyway. Other athletes know what the helmet is for.
By the way, what's the difference between looking like "that guy" and being "that guy"? Maybe you are "that guy"!
But basically, get a grip and stop being "scared" of what other people think. That's ridiculous.
If you want to wear it, wear it.
Having said that, I wouldn't wear a TT helmet for training except to test it and/or get used to it. A normal road helmet will be safer and more comfortable for your routine rides.
