I have anon hawkeyes and love them. I tried on the Smith I/O's but felt like they too small. The Dragon APX's look awesome! They might be my next pair. To answer the question though, try on a few different ones. Try all the oversized ones you can. Some might actually be too big.
The hard part about this is where? Where can I go to try on multiple brands? I've checked some sporting stores, but they haven't really had too much to look at. I've always got gogs online..
