I’m going to bump this post up because I am looking into a Fearless by Martin. I have a 4yo who is super wide and probably won’t be thinning down as he gets older. 

Are we there any other bird of input on these saddles? Martin website says only 7” gullets avalaible. That true? 

I really like mine! I have a couple flat backed horses with bulder shoulders that it fits great. It has an interesting seat that sits you center and a little bit forward but still somehow gives you a lot of security. The fenders are very free moving and offer unlimited movement. I love this saddle on a horse I have to ride really aggressive.
