i have successfully used suicide hubs on my winter training conversions for years. I do run full brakes with hoods. Hell, I don't even use loctite, just rotafix the cog onto the hub with grease. This allows for easy gear changes as I get stronger and it gets closer to race season. If you are going to run brakeless or even just a front brake, I suggest picking a cheap fixed gear wheel for piece of mind alone.
