I have a 2016 Deluxe and a Mustang Deluxe seat and love both. However, I would add that even though the Mustang provides great sacrum support, it doesn't really support the lumbar. If you absolutely must have a true backrest, this might be a consideration. The seat also sits you back a little, and the additional support is angled slightly backwards. So if you have a short reach then you will be leaning forward toward the bars and away from the support. I'm 6' with a 31 inch inseam and have Heli bars to pull the bars back quite a bit. In any case, this is a great forum for ideas, support, and help, and it's an incredible bike. Good luck!
