Curing in salt will make it salty. No way around that. If you buy one of the commercial curing mixes they use nitrates/nitrites etc and it will taste much less salty. One of the mixes has smoke powder in it which isn't for the purists but does work.
I would smoke after curing, not instead of. I don't believe that just cold smoking will preserve it without curing as well.
Anybody do differently though ?
