Double Bend vs Single Bend: Both the Spider Tour and the Spider X offer a face-balanced version (suited to a straight-back, straight through stroke). However, the face-balanced Spider Tour has a double bend, whereas the face-balanced Spider X has a single bend. The end result is the same, but the single bend is definitely the more attractive option.
L Neck vs Flow Neck: The Spider Tour offers an L-Neck version with 21° of toe hang. The Spider X has a flow neck version with 22° of toe hang. Again the end result is pretty much same, but in this instance, the L Neck of of the Spider Tour is the better looking choice, if you prefer the L Neck style.
Maximum Toe Hang Option: The Spider Tour has a small slant option with 32° of toe hang. This is slightly more than the small slant Spider X, which has 30° of toe hang. Admittedly it’s only a 2° difference, but it’s worth pointing out.
