Uhh, the heel on these exactly the same as you'd find in the STH16, just with a different spring (and exactly the same as the STH14 LAB). The toe piece, while similar to a z series, is quite a bit better than that in the STH12. As good as the toe piece on the STH14 LAB/STH16? Personally, I don't think so, but others will argue.
All that being said, take $180. There are STH16s floating around here and other places for about the same price.
