1st Scarpa Tx & Bomber Bishop Review
The 1st Generation Scarpa Tx fits fine in the Bomber toe piece, until you flex the boot that is. Without a duckbill the Bishop becomes the most neutral binding I have skied. If you hold a good stance and pressure the back ski properly the Scarpa Tx feels like a 75mm boot in the binding, but if you make a boo boo you are straight onto the toe of the boot.
The NTN standard will fit in a Bomber Bishop binding, but I wouldn't recommend it.
