Hi everybody of the scuba diving community!
I know this topic has been posted MANY times before, but from what I have found none of the previous threads match my circumstances perfectly or are recent enough due to updates in regulator technology. So now it is my turn to start a new thread on "cold water regulators".
My background: I am a newly "open water" certified diver who lives in Stockholm, Sweden. I've done about six open water dives in the Stockholm area but have always used rental equipment from my LDS (dry suit, BCD and regulator set). All of my dives were in February and March with water temperatures at 1-2°C, but due to the cold temperatures and cheap rental regulators (Scubapro but don't know the model) I kept getting free flows due to regulator freezing. NOT FUN when you have to keep going up to the surface every 10min due to free flows, so now I am looking to get my own regulator set.
I'm the type who likes to buy quality from the start instead of something half good now and having to buy again something better in the future. I'll continue to dive in the Stockholm area throughout the year but will likely also travel with my gear to warmer climates (did my first "try scuba diving" in Florida and loved the coral and wildlife). I plan on getting an "advanced open water" as well as "enriched air nitrox" certificate but am pretty unlikely to do tech/cave diving and wreck penetration, but who knows...
From my research in articles and lists of top regulators I have come to the following conclusions:
The setup I am planning is my own sort of long-ish hose (mix between tech/long hose and recreational setup) with some sort of swivel joint at the second stage (for comfort) and free flow shut-off switch on the hose (in case of second stage free flow). What are your thoughts on such add-ons when it comes to cold water performance and freezing? Would there be any problems with them being leak or freeze points?

From my research in articles and lists of top regulators I have come to the following conclusions:
- The regulator MUST be environmentally sealed.
- It has to be DIN for me.
- I'd like two HP ports, one for a simple brass SPG and one for a transmitter for my dive watch.
- Piston seems to have better air flow characteristics according to articles i've read, but environmentally sealed regulators seem to be mainly diaphragm.
- I'd like both the first and second stages to be balanced if not over-balanced.
- Nitrox ready.
- Adjustable second stage for cracking pressure and venturi effect.
