Dear mr.boz, my name is michaela lee and iam from ridgecrest california iam 13 years old. I ride endurance rides that are 65 miles long in 10 hours, as well as pleasure riding in the high seirras. My horses name is flash he is 13 years old. I have experienced with my other saddles back problems and tenderness issues. I had bought the boz kit saddle from you with a little help i had put it together within 45 minutes. As iam conditioning my horse for the bridgeport endurance ride in august i have experienced many good things. As far as my riding posture, my horses back issues are non existent . I will always recomend this saddle for people that spend many hours in the saddle. Thank you so much! -michaela lee - 17699770966
