I've tried using heal guards and whenever I'd land off of a jump my heals would slam into the guards. I actually dented one of my aluminum guards, so no guards for me
those xfr nerfs are great but ur boot catches when u kick i have to kick with the heel of my boot
another idea if u dont want heel guard just get a plus 6 or longer swingarm lol
i never had that problem with my banshee with my plus 6 on her B)
