I've read all of the reviews i could find and have'nt learned much. It seems both tanks are great and both stink, depending on who you ask. i'm not really concerned about comfort, I know I'll get used to the ergo's no matter. But I would like to here from anyone with direct knowlege relating to the install and fit of these tanks. Do the mounts line up? Do the shrouds fit? Does the petcock seat? And how about fuel line routing? Any heat related issues? That sort of thing. I just wanna get it right the first time. Thanks!
