I am not real crazy about the "prison rig" frame since it has a blocky bottom to it, I feel like that's a waste kinda. I really like the middle one. I got a dan kubin dd today in a trade and I'm hooked on that, also got a custom dd from Darkside machines that has become a daily runner . I think I'm slowly moving toward all dd setup lol one of these might find it's way to my toolbox
