I've done many kms on a rotafixed suicide hub, but I used the brakes for stopping ... and invested in a fixed gear wheelset as soon as I could afford it.
I've also spun a suicide cog off, which is why I learned to rotafix
If you're going to use your legs for stopping, any suicide setup is just delaying the purchase of track wheels, using goops and glues just makes the delay expensive. In the meantime, rotafix is your friend.
