I trust your expertise and devotion to what you do blindly all the time and ready to sign up to any new product you have in mind. Nevertheless I think you should give a try to a solution without the NR wire. In my experience the Penelope and Ody works great, nothing match the performance if everything is done right at the set up. On the other hand there can be problems, which always come from joining NR with R wires. Jumping ohms, sometimes not 100% performance etc... I am sure all of us who use your great devices have experienced these. This might lead to creating a new set up every 2-3 days.
I know if everything is done right the above is not happening. But even for me, who is using GG stuff for more, than a year its a kind of luck situation. Creating a good join is one thing, the other is how the small "nuts" created by screwing together the wires behave when installing the coil in the center piece. The slightest miss positioning might lead to issues.
I also know that using pre-made wires this is not an issue, but I believe your mail goal is to give people hassle free devices with very easy set up (no tools required). Always worrying about when new pre-made will be available at vendors is not in line with that, I guess.
There is a certain type of Russian device which has a different feeding approach and does not require NR wires. I do not think that it matches the outstanding holy trinity of Penelope (Taste / Vapor production / TH) but I have to admit it is much easier to set up.
Also I am aware that some (non-Chinese) copiers are using your feeding method but implementing a set up which does not require NR wires.
I am not saying that this is the way to hit and I am pretty sure you have your good reasons to keep on using NR in your devices, but please Imeo give it a thought as this is the only part of your devices which creates the most headache for your customers.
