I currently have CX403 size 43.5 in a standard width which have worked well for me for a number of years. I am looking to get the CX400. They share the same last as the CX403 but have been caught out previously with different lakes from the same last having different widths/toe boxes (e.g CX302) so want to get some advice before ordering a pair of CX400. Any thoughts would be much appreciated

What is the best way and device to measure tilt? I measure the front half of the saddle (Selle San Marco 3dfx) with the app saddle adjust on my iPhone but as it has a camera bump the readings are off. Any other techniques?
