The Standard LT tree has a 6.5" Gullet
The Standard SE tree has a 6.75" Gullet
That being said, you can order either of those trees with wider gullets, but I did not see Steele's designation of +1/4 or +1/2 that would say they were non-standard, but maybe the Saddle Maker ordered them wider than standard and Steele forgot to mark them with the addition....
Joby's tree looks like it has the correct angle on the front of the bar but way too wide, the back of the bars are not flat enough but angles are good.
Bart's tree also has the correct angle in the front of the bar but way too wide, the back of the bar has the wrong angle.
May all your Trails be happy and safe ones
