Richardson gives me a great deal so I'm very loyal to them because they are a sponsor... that being said.. I've never seen anyone complain about a Butlerbuilt and there are a million of them sitting on the shelves if you need one. I've seen a few Ultra Shields bend, and I just don't like the Kirkeys. I can tell you Steve Richardson will be more than happy to help you out because he doesn't make alot of sprint seats. I find my Richardson seats to be just as thick, sturdy and well built as the Butlerbuilts; and they are 22lbs (6lbs lighter than Butler). That being said... just do your research and don't skimp out on $300 when it comes to safety gear. Good luck!
