Thanks Smokin Monkey. Wade's brine mix was 6litres water and 316 grams of salt, (plus sugar and nitrite). The recipe I followed called for 1.5 litres water and 400gms salt! Little wonder the result was salty then!
Wade's of course was hot smoked, and I'm cold smoking mine with the intention of pan frying it. I'll try it later, too late to brine now. For the future though I'll try Wade's brine for sure.
