Here's the problem, I'm 5' 8" and weight 185. I have NO Butt! I need a good seat that will hold me in place. I keep slideing forward on the OMB seat. I purchased a "custom" Hartco seat and it would not fit the trike correctly, and rubbed the paint off on my fuel tank. They did adjust the leg area of the seat for me, but it still just wasn't the right seat. I am now trying the Ultimate Midrider, but it raises me about an inch and gives me an insecure feeling when flying down the highway. Is there a perfect seat out there for a guy like me??
