I randomly walked into a store today and they had their FASE Katana and Blaster samples on the display for people to play with. They weren't bolted to a board but I could mess with the ratchets and other parts. From the testing I could do, the ankle strap was easy to use and I'm not concerned about the lever-highback connection durability. I could also pop it apart reasonably easily by just smacking the highback forward with my hand, so it should be a piece of cake when using a boot to kick it down.
The toe strap webbing for the Blaster is definitely more flexible than for the Katana (grain of salt, these were sample bindings so it may change).
The Blaster sample was the black body but with grey accent colors instead of the red ones shown for the product version. I know I'm probably in the minority, but I liked the grey better. I wonder if they will sell the color parts as spares, since that would allow people to swap out accent colors for the other options in the model.
I'm definitely interested in picking up a pair. I just need to decide which binding makes the most sense for how I ride - not the Thirty Two, I'm not freestyle. I'll probably put my Flow NX2-TM bindings on my Coda and the FASE on my Superposition.
