With or without chaintugs, if your wheel is slipping enough to break chains you need to sort out your axle nuts and htfu when tightening them. Basically you shouldn't be relying on tugs to hold your wheel in place.. that's what the nuts are for.
My track bike has chrome dropouts, these are a nightmare with standard phil wood hub, the bolts on phils are not grippy or big enough to grip the dropouts not matter how hard you tighten them. I ended up getting the phil chrome domes which are basically something that should be supplied with the hubs but they sorted it fine without having to use tugs. Tugs seem a total faff and I'm not keen on the look of them.
