Routing a rear brake cable through 3 cable stoppers

As far as I can think, there are four ways of dealing with the cable run to the rear brake:

• Using clips as BrickMan mentioned.
  
• Using welded / brazed on guides that the outer runs through.
  
• Using cable stops which only the inner runs through.
  
• Internal run through the top tube which can either have stops or need outer the whole way through.
  
  

If you have welded / brazed on guides you don't need clips.

Ok basically I've got 3 welded on cable guides on top of my top tube, what I think i need are some cable casing caps that are flared? or just bigger at the end so my outer cable doesn't go through my guides, then I could just run a bare inner between them. Otherwise running the outer through all 3 will give a 'spongy' brake, my friend did it and his brakes were naff

Thanks
