This lightweight custom saddle from Rider's Choice Saddlery features a unique Steele Equifit tree called the "X," which is their “Broad-Backed Full Quarter Horse Plus+” tree. It has a wider front (~100 degrees), and rear bar angle (~145 degrees). The larger angle allows for a broad wither and larger shoulder muscles, plus a more open bar angle (~130) through the rider’s legs facilitates the horse raising his back through collection and core development. When combined with a larger gullet width, it sits much better on really broad-backed horses. The wooden tree is fiberglass reinforced, which locks out moisture and adds another layer of strength to the tree, adding to the longevity of your saddle. 
S/N: 32814, confirmed the build details with Jerry Payne of Rider's Choice Saddlery

7.25" gullet width on the bare tree
100 degree angle to the gullet
130 degree angle to the mid-back
145 degree angle to the loin area 
(This saddle is ideal for an extra-broad-shouldered, beefcake, "bull-dog" built horse)

Tree size:  21" Steele Equifit "X+1/2," "Silcush-padded" solid wood tree, with fiberglass reinforcement. The Silcush padding will fill in any gaps that don't fit closely to the horse, and it also creates a bit more flare on the front of the tree, allowing additional shoulder relief for that large, progressive shouldered horse.
Seat: 16.5" on the bare tree, roughout out ultra-plush padded seat with a narrow twist for supreme comfort on long trails! Fits closer to a 16". 
Leather: Premium Hermann Oak drum dyed leather in dark brown, with braided border stamping.  
Weight: ~25 lbs 
Rigging: Dropped D-ring in 7/8ths position. You can Y-rig this saddle, if desired, or use a separate flank cinch for a traditional double rigging, if you prefer.  
Total saddle length: 24", although the front 2" is just bare soft leather, so it won't trap the shoulder blades
Year built: 2014
