This is only my opinion ... so please disregard as needed. Hyacinth's idea of a front harness sounds good ...
but here are my additional thoughts (hope they help). With a pulling dog like yours, with a strong neck and high excitement its true that a correction chain or martingale is likely just to choke the dog (it wont overide its pain and stop pulling) regular harnesses encourage pulling.
Front harnesses or halti are the only way to go for these breeds, but only while you are bonding or trusting their off lead behaviour. Walking your guy on lead is very unlikely to drain much energy at all unless you go for an hour or so plus.
With a dog like you describe your goal is recall then as much off lead time as you can get to drain their energy. Unless you do that you will have many behavioural problems coming your way from excess energy. Walking a dog should never involve saw arms. I have only changed over from a correction chain to a martingale this year, as my dog has gotten to that point after five years.
Good luck on your mission!
