I haven't had a chance to try on either the Splinter or the Square Whisker yet, but am I right in thinking they're a wider/bigger fit than the Square Wire 3.0? I really like the design of both frames, but I always found the 3.0 just a *bit* lacking in coverage.
I tried the Splinter for the first time yesterday. I like them better than the Square Whisker, but can't comment on the width. I recommend the black/blue frames with black polarized lenses.
I got to try the Square Whisker today and I liked it very much. I think the lens cut is nicer than the standard Whisker cut. It's a real sleek simple wire.
