Agreed. I don’t call anything “undersized” until it’s 52mm and below. There’s a gray area and nobody to enforce the categorizations (thankfully!), but to me even 52.x is mid-sized. They keep calling the Werrd Minute an “undersized” throw, but it’s got more in common with the Puffin than with a Supra.
Looking forward to seeing more about the Amplitude! If it’s at ano now, it won’t be TOO long before the shots we’ve all been waiting for.
